Abstract |
|
In the image watermarking community, developing a robust watermarking method has attracted increasing attention in recent years. In this paper, robust image watermark algorithm is proposed which is based on histogram shape that resists against geometric attack and signal processing attack by using invariance property of histogram to scaling and statistically independent to the position of pixels in the image. In this method, watermark is embedded by shifting pixels within group by maintaining histogram shape. At watermark detection site, watermark is detected by calculating relationship between bins of group. Watermark scheme is blind in nature. |
