Sift-based image copy-and-paste forgery techniques
no vote
Image-based replication sift paste tamper detection algorithm first extracted sift feature, using a hybrid programming method for extracting sift online offer, then sift feature matching with RANSAC algorithm eliminate mismatch right, and finally with the segment will copy and paste the original block and block matching connect the dots. This calculation algorithm is resistant to various processing operations, such as rotation, scale scaling, adding noise and the like and several combinations.

Image copy and paste tamper detection using SIFT feature
4.3
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.

Firstly, SIFT features are extracted. The SIFT features extracted here are extracted by C + + code, and then g2nn matching and matching are performed
