WebFeb 4, 2011 · The sift function only works in greyscale, so the input should be 1 channel as well. If the input has 3 or 4 channels instead of 1 (such as RGB, or RGB with alpha) , sift will convert the input image into greyscale before running its algorithm. You can convert to greyscale yourself before using sift with
