WebThere are mainly four steps involved in SIFT algorithm. We will see them one-by-one. 1. Scale-space Extrema Detection. From the image above, it is obvious that we can't use the same window to detect keypoints with different scale. It is OK with small corner. But to detect larger corners we need larger windows.
