WebAug 22, 2024 · TL;DR: The mask parameter is a 1-channel numpy array with the same shape as the grayscale image in which you are trying to find features (if image shape is (480, 720), so is mask). The values in the array are of type np.uint8, 255 means "use this pixel" and 0 means "don't". Thanks to Dan Mašek for leading me to parts of this answer.
