WebThe normalise parameter of skimage.feature.hog was removed due to incorrect behavior: it only applied a square root instead of a true normalization. If you wish to duplicate the old behavior, set transform_sqrt=True. skimage.measure.structural_similarity has been removed. Use skimage.measure.compare_ssim instead. http://www.iotword.com/2097.html
