I see there is HOG descriptor implemented within scikit image, I wonder how can I reused or compare exmples given http://scikit-image.org/docs/dev/auto_examples/features_detection/plot_hog.htmlwith OpenCV where I can find http://docs.opencv.org/3.1.0/d5/d33/structcv_1_1HOGDescriptor.html.I want to intialize and compute HoG descriptor with both same parametrs. How and which the hog paramerts from scikit relates to OpenCV one? Anyone can help?
