In one code segment, I once saw an approach of filtering image values as follows using cv2. In Scikit image, if I want to realize the same functionality, how to do it?

import cv2 img = cv2.threshold(img, 0.5, 1., cv2.THRESH_BINARY)[1].astype(np.uint8

How about: from skimage import img_as_float, img_as_ubyte img = img_as_float(img) img_thresholded = img_as_ubyte(img < 0.5) Stéfan
