| 摘 要： | 提出了一种在JPEG2000中实现的数字水印方案,选择了离散小波分解后,在低频子带嵌入水印,保证了水印的不可见性;该方案选择了对JPEG2000彩色多分量图像的Y分量嵌入Arnold变换水印,简化了水印的检测.实验结果表明,该方案能抵御压缩、模糊和锐化等攻击,具有较好的鲁棒性.

| Abstract: | A digital watermarking algorithm for JPEG2000 image is presented.The digit of bit operation in low frequency sub-band after discrete wavelet transformed,which ensured the watermarking's imperceptibility;Embedding watermarking which transformed by Arnold in Y component could simplify watermarking detection for JPEG2000 several components color images.The result of the experiment show that the algorithm could withstand a lot of attacks,such as against compress,blurring and sharpening,etc,and had good robustne... |
