WebThe basic Thresholding is also called Binary thresholding. In this for every threshold value, we apply the same pixel. If the pixel value is less than the set threshold, it is set to 0, else to the highest value. Some techniques/methods are : cv2.THRESH_BINARY – Value is set to 255 only when pixel intensity is more than set threshold value, else 0.
