Abstract :
Digital watermarking technique embeds copyright information into multimedia signals so as to perform its protection and authentication. Existing digital watermark algorithms are mostly designed for gray images but not many are for color images. This paper presents some color image watermark methods proposed in recent years so as to give help for researchers to study deeply.
