| Summary: | 碩士 === 玄奘大學 === 資訊科學學系碩士班 === 96 === Watermarking methods are presented to keep the ownership of media content. Recently, study of reversible watermarking methods is popular because of recovering the original image from a watermarked image after extracting the embedded watermarks. This thesis presents a continuous zero replacement based reversible image watermarking approach that works on spatial image pixels. The proposed confusion avoidance procedure prevents confusion during embedding and extraction. Experimental results demonstrate that the proposed approach can work on different bit planes to increase embedded quantity.
