Abstract
This paper presents a blind watermark algorithm of multi-wavelet domain based on neighborhood and FCM. The watermark embedding texture sub-blocks are obtained adaptively on the multi-wavelet domain middle-frequency coefficients by applying FCM based on the human visual system. A binary image is embedded to texture sub-blocks, this algorithm can get a watermarked image with perceptual invisibility and strong robustness. In order to improve the security and robustness, the watermark is scrambled before embedded, and is repeated when embedded.Experimental results show that the algorithm is strongly robust for the common image processing techniques such as JPEG compression, cropping,sharpening salt and pepper noise, filtering and so on.关键词
