Watermark research against RST distortion based on SIFT implemented using Matlab
Wen Jia · Microcomputer Information · 2011
Based on the principle analysis of SIFT,introduce the key reasons that SIFT can endure RST distortion,then give out the implementation using Matlab program,and propose a digital watermark scheme which can endure RST attack based on SIFT,by the way,propose a general definition for image special points,and discuss the general and idle requirement for digital watermark special points.
