摘要: Reversible watermarking inserts watermark into digital media in such a way that visual transparency is preserved, which enables the restoration of original from watermarked one without any loss quality. It has various applications, where high capacity and quality are major requirements. This paper presents new effective multi-round embedding scheme for differential histogram-based reversible satisfies requirements application. The proposed technique exploits row-column cross scanning to fully utilize locality images when phase message inserted image. Through experiments using multiple kinds test images, we prove presented algorithm provides 100% reversibility, effectiveness embedding, higher quality, while maintaining induced-distortion low.
