Digital Watermarking Technology for JPEG2000 Color Image
Jianxin Yu · Jisuanji gongcheng · 2004
The paper presents a digital watermarking algorithm for JPEG2000 color image. The digit of bit operation in data pretreatment is as an embedded factor of watermarking, which adapts to different grain and color image better. The lower limited factor is introduced to the process of extraction, which improves the definition of extracted watermarking effectively. The results of the experiment show that the algorithm can withstand a lot of attacks, and has great robustness.
