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 In this chapter, 1. We will mix up the feature matching and findHomography from calib3d module to find known objects in a complex image. See more So what we did in last session? We used a queryImage, found some feature points in it, we took another trainImage, found the features in that image too and we found the best matches … See more First, as usual, let's find SIFT features in images and apply the ratio test to find the best matches. Now we set a condition that at least 10 matches (defined by MIN_MATCH_COUNT) are to be there to find the object. … See more
