WebFeb 1, 2024 · Call the .apply method on the CLAHE object to apply histogram equalization; It’s a lot easier than it sounds, requiring only a few lines of code: gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY) … • The size of the neighbourhood region is a parameter of the method. It constitutes a characteristic length scale: contrast at smaller scales is enhanced, while contrast at larger scales is reduced. • Due to the nature of histogram equalization, the result value of a pixel under AHE is proportional to its rank among the pixels in its neighbourhood. This allows an efficient implementation on specialist hardware that can compare the center pixel with all other pixels in the neighbourhood… peter thyssen
