High Precision Image Authentication Watermarking Algorithm for Image Tampers Recovery
摘要
Abstract
Concerning the shortage of the tamper recovery performance in the existing semi-fragile watermarking algorithm, the authors propose a precise two-watermarking algorithm. The algorithm uses the authentication watermarking for image authentication and tamper location; the recovery watermark is tampered image reconstruction. The simulation results show that the proposed algo-rithm has precise tamper localization, and can effectively recover the tampered content.关键词
