Abstract :
A novel digital watermark against RST distortion based on SURF is proposed. The algorithm is the second watermark, SURF is fast than SIFT, so that the algorithm is faster, and the ability against RST is nearly the same with feature based SIFT. The watermark algorithm use odd-even detector properly to avoid the distortion procedure when watermark is embedded.
