Image copy and paste tamper detection algorithm based on SIFT, the algorithm first extracts SIFT features, uses the hybrid programming method of sift extraction provided on the Internet, then matches and clusters SIFT features, then uses RANSAC algorithm to eliminate mismatches, and finally uses line segments to connect the matching points in the original block and copy and paste block. This algorithm can resist all kinds of post-processing operations, such as rotation, scaling, adding noise and their combinations.
