Scale invariant feature transform (SIFT) is a computer vision algorithm used to detect and describe the local features in the image. It looks for the extreme points in the spatial scale, and extracts the position, scale and rotation invariants. This algorithm was published by David Lowe in 1999 and summarized in 2004.
