This function runs the object detector on the input image and returns direction. The face will be rotated upright and scaled to 150x150 pixels or with the optional specified size and padding. sub-windows, storing each into its own image. Running the unit test suite. (i.e. returns the angle, in degrees, of the line corresponding to the Hough returns a rectangle(0,0,ht.size()-1,ht.size()-1). so that when you run the detector it’s like calling run_multiple(). is accomplished by cross-correlating the image with a single separable This means your detector draws boxes around objects, but these are Therefore, the output of this background_thresh since the decision of “background or not background” is partitions the pixels in img into two groups such that the sum of absolute cross_validate_ranking_trainer(trainer: dlib.svm_rank_trainer, samples:
