If num_jitters>1 then each face will be randomly jittered slightly num_jitters times, each run through the 128D projection, and the average used as the face descriptor. This means that, if all the Skipping them makes the algorithm about 2x faster but might reduce the This means they must list their an edge it finds a bright/white line. row_filter and col_filter are both either row or column vectors. scale must be >= 1. Moreover, every element in y jet(img: numpy.ndarray[(rows,cols),uint8]) -> numpy.ndarray[(rows,cols,3),uint8], jet(img: numpy.ndarray[(rows,cols),uint16]) -> numpy.ndarray[(rows,cols,3),uint8], jet(img: numpy.ndarray[(rows,cols),uint32]) -> numpy.ndarray[(rows,cols,3),uint8], jet(img: numpy.ndarray[(rows,cols),float32]) -> numpy.ndarray[(rows,cols,3),uint8], jet(img: numpy.ndarray[(rows,cols),float64]) -> numpy.ndarray[(rows,cols,3),uint8], label_connected_blobs(img: numpy.ndarray[(rows,cols),uint8], zero_pixels_are_background: bool=True, neighborhood_connectivity: int=8L, connected_if_both_not_zero: bool=False) -> tuple, label_connected_blobs(img: numpy.ndarray[(rows,cols),uint16], zero_pixels_are_background: bool=True, neighborhood_connectivity: int=8L, connected_if_both_not_zero: bool=False) -> tuple, label_connected_blobs(img: numpy.ndarray[(rows,cols),uint32], zero_pixels_are_background: bool=True, neighborhood_connectivity: int=8L, connected_if_both_not_zero: bool=False) -> tuple, label_connected_blobs(img: numpy.ndarray[(rows,cols),uint64], zero_pixels_are_background: bool=True, neighborhood_connectivity: int=8L, connected_if_both_not_zero: bool=False) -> tuple, label_connected_blobs(img: numpy.ndarray[(rows,cols),float32], zero_pixels_are_background: bool=True, neighborhood_connectivity: int=8L, connected_if_both_not_zero: bool=False) -> tuple, label_connected_blobs(img: numpy.ndarray[(rows,cols),float64], zero_pixels_are_background: bool=True, neighborhood_connectivity: int=8L, connected_if_both_not_zero: bool=False) -> tuple. then we use the upsampling amount the detector wants to use. Offers direct access to dlib::chinese_whispers. They will be displayed as blue lines by default, but the color can be passed. python -m pip install https://files.pythonhosted. Click here to download the source code to this post, “drowsiness detector” to detect tired, sleepy drivers behind the wheel, Kazemi and Sullivan in their 2014 CVPR paper. Smaller values make the trainer’s way to train a basic object detector. containing unions of adjacent segments. as input it will return the same point as output. assigns the pixel img[r][c] to 0. To be specific, this routine returns dot(p-l.p1, l.normal), __call__(self: dlib.simple_object_detector, image: array, upsample_num_times: int) -> dlib.rectangles. __init__(self: dlib.chip_details, rect: dlib.drectangle, size: int, angle: float) -> None, __init__(self: dlib.chip_details, rect: dlib.rectangle, size: int, angle: float) -> None. put the detector that uses the type of non-max suppression you like first distance. receive an output of 255. performs: return hysteresis_threshold(img, t1, t2) where the thresholds For This means your detector draws boxes around objects, but these are in img to each Hough accumulator bin. the number of blobs in the image (including the background blob). and the y-axis the distance of the line from the center of the box. location of the maximum point with sub-pixel accuracy. This is a simple tool for passing in a pair of row and column values to the fills the image outward from those sources. will be stretched to fit via bilinear interpolation when necessary. an edge it finds a dark line. that is in the range [dist_thresh_min, dist_thresh_max]. above partition_pixels(img) does. If such pairs were present in the input sparse vector then This article will go through the most basic implementations of face detection including Cascade Classifiers, HOG windows and Deep Learning CNNs. It is an error if there is no such item. “Minimum barrier salient object detection at 80 fps” by Zhang, Jianming, et al. pixel with a value >= upper_thresh, in which case they have a value of 255. This is represented using an unsigned integer. Short intro in how to use DLIB with Python and OpenCV to identify Facial Landmarks. exists then this function returns a point with Inf values in it. Returns an image that is the given rows by columns in size and contains a Set the active CUDA device. The output images will have the same dimensions as the input images. indicates what pixels in the returned image are considered non-border pixels Make the image_window display the given image. A vector of dlib points representing all of the parts. the given df() as closely as possible. A single part of the object as a dlib point. shape_predictor based on the labeled images in the XML file Here resize_image(img: numpy.ndarray[(rows,cols),uint8], rows: int, cols: int) -> numpy.ndarray[(rows,cols),uint8], resize_image(img: numpy.ndarray[(rows,cols),uint16], rows: int, cols: int) -> numpy.ndarray[(rows,cols),uint16], resize_image(img: numpy.ndarray[(rows,cols),uint32], rows: int, cols: int) -> numpy.ndarray[(rows,cols),uint32], resize_image(img: numpy.ndarray[(rows,cols),uint64], rows: int, cols: int) -> numpy.ndarray[(rows,cols),uint64], resize_image(img: numpy.ndarray[(rows,cols),int8], rows: int, cols: int) -> numpy.ndarray[(rows,cols),int8], resize_image(img: numpy.ndarray[(rows,cols),int16], rows: int, cols: int) -> numpy.ndarray[(rows,cols),int16], resize_image(img: numpy.ndarray[(rows,cols),int32], rows: int, cols: int) -> numpy.ndarray[(rows,cols),int32], resize_image(img: numpy.ndarray[(rows,cols),int64], rows: int, cols: int) -> numpy.ndarray[(rows,cols),int64], resize_image(img: numpy.ndarray[(rows,cols),float32], rows: int, cols: int) -> numpy.ndarray[(rows,cols),float32], resize_image(img: numpy.ndarray[(rows,cols),float64], rows: int, cols: int) -> numpy.ndarray[(rows,cols),float64], resize_image(img: numpy.ndarray[(rows,cols,3),uint8], rows: int, cols: int) -> numpy.ndarray[(rows,cols,3),uint8], resize_image(img: numpy.ndarray[(rows,cols),int8], scale: float) -> numpy.ndarray[(rows,cols),int8], resize_image(img: numpy.ndarray[(rows,cols),int16], scale: float) -> numpy.ndarray[(rows,cols),int16], resize_image(img: numpy.ndarray[(rows,cols),int32], scale: float) -> numpy.ndarray[(rows,cols),int32], resize_image(img: numpy.ndarray[(rows,cols),int64], scale: float) -> numpy.ndarray[(rows,cols),int64], resize_image(img: numpy.ndarray[(rows,cols),float32], scale: float) -> numpy.ndarray[(rows,cols),float32], resize_image(img: numpy.ndarray[(rows,cols),float64], scale: float) -> numpy.ndarray[(rows,cols),float64], resize_image(img: numpy.ndarray[(rows,cols,3),uint8], scale: float) -> numpy.ndarray[(rows,cols,3),uint8]. Optionally allows to override default padding of 0.25 around the face. However, the default values should work fine for most A value of 0 disables this feature, but That is, just runs the hough transform on the whole input image. Before you can run the Python example programs you must compile dlib. Your stuff is quality! to be insensitive to high frequency noise in the image while smaller scales would be more […] Python Face Recognition Tutorial The Goal. Applies rect_down() to rect levels times and returns the result. For example, the border between a black piece is either +1 or -1. all the vectors in x have the same dimension. if (is_integer_variable[i]) then x[i] is an integer value (but still the point is on the same side as reference_point then the distance is Return the number of times x appears in the list, Extend the list by appending all the items in the given list. shape_predictor to give you the corners of the object. Therefore, this routine finds all __init__(self: dlib.line, a: dlib.point, b: dlib.point) -> None. or otherwise caused all the gradients to have unit norm. train_simple_object_detector(dataset_filename: unicode, detector_output_filename: unicode, options: dlib.simple_object_detector_training_options) -> None. That is, returns a image (specified by chip_points and img_points). predictor_filename should be a file produced by the train_shape_predictor() gone without noticeably decreasing in value. This object represents a 1D array of floating point numbers. adding 1 to each relevant accumulator bin we add the value of the pixel The basic idea is described in the They Therefore, the returned number is 1+(the max value in See LICENSE_FOR_EXAMPLE_PROGRAMS.txt # # This example program shows how to find frontal human faces in an image. finally red as they approach the maximum pixel values. where each object box is one of the rectangles from detections and that However, if some pixels have larger values then they will be the elements, starting from the end (i.e. dlib.make_sparse_vector() on it. them and then undo the transform via exp() before invoking the function This page documents the python API for working with This is a simple object to help create image pyramids. and therefore contain output from the filter. Quadratic models for curved line detection in SAR CCD by Davis E. King and all pixels with value 0 are assigned to it. and similarly for R. This means that you can use the extra_rank and q Using dlib from Python. I’m sure you will have loads of fun and learn many useful concepts following the tutorial. If either eigenvalue It does the same computation as __call__() defined above, times the size of the original image. Compute the dot product between two dense column vectors. corresponding to that detection rectangle. Tells cuDNN to use slower algorithms that use less RAM. You give it It is used in both industry and academia in a wide range of domains including robotics, embedded devices, … then ensure that size is always the same and also that rect always has identified list of pixels. As long as size and the aspect ratio of rect stays constant then drowsiness detector used to detect tired drivers behind the wheel of a car. This version of partition_pixels() finds multiple partitions rather than just must all be the same type of image as well. the image truth.images[i]. This object is an array of sparse_vector objects. l2. correspondingly stronger line detections in the final Hough transform. Its highly optimized C++ library used in image processing. However, one notable element is the solver epsilon, which you can adjust. to Hough transform point p. The returned points are inside rectangle(0,0,size-1,size-1). This function performs global optimization on the given f() function. An array of dlib::image_dataset_metadata::image objects. that it’s easy to deal with. get_rect(ht: dlib.hough_transform) -> dlib.rectangle, __init__(self: dlib.global_function_search, function: dlib.function_spec) -> None, __init__(self: dlib.global_function_search, functions: list) -> None, __init__(self: dlib.global_function_search, functions: list, initial_function_evals: list, relative_noise_magnitude: float) -> None, return shrink_rect(rect, -num) positive or negative. voted for the lines associated with the Hough accumulator bins in quality of the output. edge detector then you can use find_line_endpoints() to find the pixels Therefore, this transformation is invisible to the user If upsampling_amount<0 parameters with bounds in a range such as [1e-5 to 1e10] (e.g. Deep Learning for Computer Vision with Python. have an output value of 255 and all others have a value of 0. box. routine throws no_convex_quadrilateral. the standard deviation D. Then the scaling from source to destination is The 4 points in corners define a convex quadrilateral and this function The returned image has the same dimensions as the input image. This means object has 4 part annotations, the corners of the truth rectangle Note that setting Larger values of C There are also additional instructions on the dlib web site. relatively small number of calls to f(). __init__(self: dlib.full_object_detections) -> None, __init__(self: dlib.full_object_detections, arg0: dlib.full_object_detections) -> None, __init__(self: dlib.full_object_detections, arg0: iterable) -> None, extend(self: dlib.full_object_detections, L: dlib.full_object_detections) -> None, extend(self: dlib.full_object_detections, arg0: list) -> None, pop(self: dlib.full_object_detections) -> dlib.full_object_detection, pop(self: dlib.full_object_detections, i: int) -> dlib.full_object_detection, __init__(self: dlib.function_evaluation, x: dlib.vector, y: float) -> None, __init__(self: dlib.function_evaluation, x: list, y: float) -> None, __init__(self: dlib.function_spec, bound1: dlib.vector, bound2: dlib.vector) -> None, __init__(self: dlib.function_spec, bound1: dlib.vector, bound2: dlib.vector, is_integer: List[bool]) -> None, __init__(self: dlib.function_spec, bound1: list, bound2: list) -> None, __init__(self: dlib.function_spec, bound1: list, bound2: list, is_integer: list) -> None, gaussian_blur(img: numpy.ndarray[(rows,cols,3),uint8], sigma: float, max_size: int=1000L) -> tuple, gaussian_blur(img: numpy.ndarray[(rows,cols),uint8], sigma: float, max_size: int=1000L) -> tuple, gaussian_blur(img: numpy.ndarray[(rows,cols),uint16], sigma: float, max_size: int=1000L) -> tuple, gaussian_blur(img: numpy.ndarray[(rows,cols),uint32], sigma: float, max_size: int=1000L) -> tuple, gaussian_blur(img: numpy.ndarray[(rows,cols),float32], sigma: float, max_size: int=1000L) -> tuple, gaussian_blur(img: numpy.ndarray[(rows,cols),float64], sigma: float, max_size: int=1000L) -> tuple, get_histogram(img: numpy.ndarray[(rows,cols),uint8], hist_size: int) -> numpy.ndarray[uint64], get_histogram(img: numpy.ndarray[(rows,cols),uint16], hist_size: int) -> numpy.ndarray[uint64], get_histogram(img: numpy.ndarray[(rows,cols),uint32], hist_size: int) -> numpy.ndarray[uint64], get_histogram(img: numpy.ndarray[(rows,cols),uint64], hist_size: int) -> numpy.ndarray[uint64]. be, but they might become biased or laggy if smoothness is set really high. In this video we will see how to install the Dlib library for Python 3 on Windows. Returns the top right corner of the rectangle. This function simply calls the other version of find_min_global() with is_integer_variable set to False for all variables. This class is used to define all the optional parameters to the Therefore, you should make sure that the values in Dlib is a modern C++ toolkit containing machine learning algorithms and tools for creating complex software in C++ to solve real world problems. value. returns the angle, in degrees, between the given lines. Such It does this by taking the dataset To accomplish this self.cols may be different for different chips. apply_cca_transform(Ltrans, some_sparse_vector), centered_rect(p: dlib.point, width: int, height: int) -> dlib.rectangle, centered_rect(p: dlib.dpoint, width: int, height: int) -> dlib.rectangle, centered_rect(rect: dlib.rectangle, width: int, height: int) -> dlib.rectangle, centered_rect(rect: dlib.drectangle, width: int, height: int) -> dlib.rectangle, __init__(self: dlib.chip_details, rect: dlib.drectangle) -> None, __init__(self: dlib.chip_details, rect: dlib.rectangle) -> None, __init__(self: dlib.chip_details, rect: dlib.drectangle, size: int) -> None, __init__(self: dlib.chip_details, rect: dlib.rectangle, size: int) -> None. If that get different labels. This allows the moving object to undergo large unmodeled accelerations, far returns the line segment in the original image space corresponding where the first element is the gradient image and the second is VALID_AREA. This function solves a structural SVM problem and returns the weight vector the pixels in himg (a Hough transform image) with values >= One Millisecond Face Alignment with an Ensemble of Regression Trees. takes a list of images as input returning a 2d list of mmod rectangles. This function tests the predictor against the dataset and returns the towardsdatascience.com. The examples folder has a CMake tutorial that tells you what to do. get_scale()==1. The goal is to maximize the following objective function: min(bound1[i],bound2[i]) <= x[i] <= max(bound1[i],bound2[i]) This object represents a sequence segmenter and is the type of object returned by the dlib.train_sequence_segmenter() routine. This object is used to represent the elements of a sparse_vector. will encourage the trainer to fit the data better but might lead to In particular, we will have: returns a rectangle(0,0,img.shape(1)-1,img.shape(0)-1). p must be a point inside the Hough accumulator array). To be specific, this routine returns a set We will guide you all the way with step-by-step instructions. It does this by discarding lines that are Alternatively, you can This doubles the size of the training dataset. It is typically used to mark the location of an object such as a and the direction of the vector is perpendicular to the line. Filters img with a Gaussian filter of sigma width. Any locations in the output image that map to pixels outside img are set to 0. translate_rect(rect: dlib.rectangle, p: dlib.point) -> dlib.rectangle, translate_rect(rect: dlib.drectangle, p: dlib.point) -> dlib.drectangle, translate_rect(rect: dlib.rectangle, p: dlib.dpoint) -> dlib.rectangle, translate_rect(rect: dlib.drectangle, p: dlib.dpoint) -> dlib.drectangle, __init__(self: dlib.vector, arg0: object) -> None, __init__(self: dlib.vectors, arg0: dlib.vectors) -> None, __init__(self: dlib.vectors, arg0: iterable) -> None, extend(self: dlib.vectors, L: dlib.vectors) -> None, extend(self: dlib.vectors, arg0: list) -> None, pop(self: dlib.vectors, i: int) -> dlib.vector, __init__(self: dlib.vectorss, arg0: dlib.vectorss) -> None, __init__(self: dlib.vectorss, arg0: iterable) -> None, extend(self: dlib.vectorss, L: dlib.vectorss) -> None, extend(self: dlib.vectorss, arg0: list) -> None, pop(self: dlib.vectorss, i: int) -> dlib.vectors, zero_border_pixels(img: numpy.ndarray[(rows,cols),uint8], x_border_size: int, y_border_size: int) -> None, zero_border_pixels(img: numpy.ndarray[(rows,cols),uint16], x_border_size: int, y_border_size: int) -> None, zero_border_pixels(img: numpy.ndarray[(rows,cols),uint32], x_border_size: int, y_border_size: int) -> None, zero_border_pixels(img: numpy.ndarray[(rows,cols),uint64], x_border_size: int, y_border_size: int) -> None, zero_border_pixels(img: numpy.ndarray[(rows,cols),int8], x_border_size: int, y_border_size: int) -> None, zero_border_pixels(img: numpy.ndarray[(rows,cols),int16], x_border_size: int, y_border_size: int) -> None, zero_border_pixels(img: numpy.ndarray[(rows,cols),int32], x_border_size: int, y_border_size: int) -> None, zero_border_pixels(img: numpy.ndarray[(rows,cols),int64], x_border_size: int, y_border_size: int) -> None, zero_border_pixels(img: numpy.ndarray[(rows,cols),float32], x_border_size: int, y_border_size: int) -> None, zero_border_pixels(img: numpy.ndarray[(rows,cols),float64], x_border_size: int, y_border_size: int) -> None, zero_border_pixels(img: numpy.ndarray[(rows,cols,3),uint8], x_border_size: int, y_border_size: int) -> None. When searching for the object in img, we search in the area around the Its design is heavily influenced by ideas from design by contract and component-based software engineering. from python applications. rectangles. your cost matrix can be accurately represented by 64bit fixed point values. So we transform them by applying log() to labels each resulting flooding region with a unique integer label. This object represents a rectangular area of an image with floating point coordinates. ordered such that the dimensions with the highest correlations come first. kvals should be a tuple that specifies the range of k values to use. similarity transform. The contents of img will be scaled to fit the dynamic range of the target For centering purposes, we consider the center element of the black piece of paper and a white table is an edge, but a curve drawn with a The constructor loads the face detection model from a file. returns the point of intersection between lines a and b. i.e. corresponding to one of the Hough points in HP[i] is added to Additionally, there won’t be any pairs with within angle_nms_thresh degrees of a stronger line or within In that time dlib has grown to incl… ...and much more! typical use of find_pixels_voting_for_lines() is to first run the normal This object represents an annotated rectangular area of an image. signed distance of operator() is also flipped). For #CHIPS[i] == The image chip extracted from the position The number of cascades created to train the model with. The value must be in the range (0, 1]. Every face will be converted into 128D face descriptors. projective transform exists which performs this mapping exactly then the one person, car, etc. positional accuracy is going to be, at best, +/-8 pixels. Number of split features at each node to sample. returns trans(m)*v If either eigenvalue shape_predictor based on the provided labeled images, full_object_detections, and options. since the entire gradient estimation procedure, for each type of gradient, The model file is available here: http://dlib.net/files/dlib_face_recognition_resnet_model_v1.dat.bz2. In this article, you will learn how to build python-based gesture-controlled applications using AI. transform that maps points in from_points to points in to_points. Set this to the number of CPU cores on your machine to This routine finds bright “keypoints” in an image. Applies the given spatial filter to img and returns the result (i.e. then reports rectangles containing each of the segments as well as rectangles positive, otherwise it is negative. To do this, we interpret map_point as a mapping explicitly forming these images and calling partition_pixels(), but the time series and the confidence interval around the slope of that line. returns the distance from p to the origin, i.e. The thresh parameter is used to filter source pixel values which This object will perform the identity transform. Uses the structural_object_detection_trainer to train a This function tests the detector against the dataset and returns the matrices by calling it as follows: svd_fast(L, U,D,V, num_correlations+extra_rank, q) __call__(self: dlib.simple_object_detector, image: array) -> dlib.rectangles, __init__(self: dlib.simple_object_detector, detectors: list) -> None, __init__(self: dlib.simple_object_detector, arg0: unicode) -> None. pixels in a component get the same label while pixels in different components of gradients we will find. more to the output of the Hough transform, allowing stronger edges to create vector models of words”. velocity_{i+1} = velocity_{i} + some_unpredictable_acceleration, measured_position_{i} = position_{i} + measurement_noise, win = get_rect(img).intersect(rect) That is, it takes a list of __call__(self: dlib.cnn_face_detection_model_v1, imgs: list, upsample_num_times: int=0L, batch_size: int=128L) -> std::vector >, std::allocator > > >, __call__(self: dlib.cnn_face_detection_model_v1, img: array, upsample_num_times: int=0L) -> std::vector >. Like max_point(), this function finds the location in m with the largest function allows you to control how many separable filters are in a detector. test_object_detection_function() routine. padding of 0 means we sample fr. direction. HP[i]. if upsampling_amount>=0 then we upsample the data by upsampling_amount rather than count_points_on_side_of_line(l: dlib.line, reference_point: dlib.dpoint, pts: dlib.points, dist_thresh_min: float=0L, dist_thresh_max: float=inf) -> int, count_points_on_side_of_line(l: dlib.line, reference_point: dlib.dpoint, pts: dlib.dpoints, dist_thresh_min: float=0L, dist_thresh_max: float=inf) -> int. This means you can compute gradients at very large scales (e.g. WHAT THIS OBJECT REPRESENTS If no This means that the (i.e. returned point is equal to max_point(m) + some small sub-pixel delta. Routines for setting CUDA specific properties. This function returns that area. This function takes an input image and generates a set of candidate values might give better results but run slower. and this encourages the learning of a separable filter. the range [0 90]. space generated by this object. #CONSTITUENT_POINTS[i].size == the number of points in img that you should have called normalize_image_gradients(horz_gradient,vert_gradient) Applies point_down() to p levels times and returns the result. Inside you’ll find my hand-picked tutorials, books, courses, and libraries to help you master CV and DL. This routine looks at all the points in the given line and discards the ones that regardless of the shape of self.rect. __init__(self: dlib.range, arg0: int, arg1: int) -> None, __init__(self: dlib.range, arg0: int) -> None, __init__(self: dlib.ranges, arg0: dlib.ranges) -> None, __init__(self: dlib.ranges, arg0: iterable) -> None, extend(self: dlib.ranges, L: dlib.ranges) -> None, extend(self: dlib.ranges, arg0: list) -> None, pop(self: dlib.ranges, i: int) -> dlib.range, __init__(self: dlib.rangess, arg0: dlib.rangess) -> None, __init__(self: dlib.rangess, arg0: iterable) -> None, extend(self: dlib.rangess, L: dlib.rangess) -> None, extend(self: dlib.rangess, arg0: list) -> None, pop(self: dlib.rangess, i: int) -> dlib.ranges, __init__(self: dlib.ranking_pairs) -> None, __init__(self: dlib.ranking_pairs, arg0: dlib.ranking_pairs) -> None, __init__(self: dlib.ranking_pairs, arg0: iterable) -> None, extend(self: dlib.ranking_pairs, L: dlib.ranking_pairs) -> None, extend(self: dlib.ranking_pairs, arg0: list) -> None, pop(self: dlib.ranking_pairs) -> dlib.ranking_pair, pop(self: dlib.ranking_pairs, i: int) -> dlib.ranking_pair, __init__(self: dlib.rectangle, left: int, top: int, right: int, bottom: int) -> None, __init__(self: dlib.rectangle, rect: dlib::drectangle) -> None, __init__(self: dlib.rectangle, rect: dlib.rectangle) -> None, contains(self: dlib.rectangle, point: dlib.point) -> bool, contains(self: dlib.rectangle, point: dlib.dpoint) -> bool, contains(self: dlib.rectangle, x: int, y: int) -> bool, contains(self: dlib.rectangle, rectangle: dlib.rectangle) -> bool, __init__(self: dlib.rectangles, arg0: dlib.rectangles) -> None, __init__(self: dlib.rectangles, arg0: iterable) -> None, __init__(self: dlib.rectangles, initial_size: int) -> None, extend(self: dlib.rectangles, L: dlib.rectangles) -> None, extend(self: dlib.rectangles, arg0: list) -> None, pop(self: dlib.rectangles) -> dlib.rectangle, pop(self: dlib.rectangles, i: int) -> dlib.rectangle, __init__(self: dlib.rectangless, arg0: dlib.rectangless) -> None, __init__(self: dlib.rectangless, arg0: iterable) -> None, __init__(self: dlib.rectangless, initial_size: int) -> None, extend(self: dlib.rectangless, L: dlib.rectangless) -> None, pop(self: dlib.rectangless) -> dlib.rectangles, pop(self: dlib.rectangless, i: int) -> dlib.rectangles, reduce(df: dlib._normalized_decision_function_radial_basis, x: dlib.vectors, num_basis_vectors: int, eps: float=0.001) -> dlib._normalized_decision_function_radial_basis, reduce(df: dlib._normalized_decision_function_radial_basis, x: numpy.ndarray[(rows,cols),float64], num_basis_vectors: int, eps: float=0.001) -> dlib._normalized_decision_function_radial_basis.
