WebAs one of the most successful feature extraction algorithms, scale invariant feature transform (SIFT) has been widely employed in many applications. Recently, the security of … 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.

They are spatial locations, or points in the image that define what is interesting or what stand out in the image. Interest point detection is actually a subset of blob detection, which aims to find interesting regions or spatial areas in an image.

Keypoint descriptor: The local image gradients are measured at the selected scale in the region around each keypoint. These are transformed into a representation that allows for significant levels of local shape distortion and c hange in illumination.
