摘要
Abstract
This paper presents an adaptive watermarking algorithm based on FCM wavelet domain.A host image is decomposed with two level wavelet transform, and the binary image is adaptively embedded according to the texture sub-blocks, these sub-blocks are obtained on the wavelet domain middle-frequency coefficients by applying FCM based on the human visual system.This algorithm can get a watermarked image with perceptual invisibility and strong robustness.In order to improve the security of the watermarking algorithm, the watermark is scrambled before embedded.Experimental results show that the algorithm is strongly robust for the common image processing techniques such as JPEG compression,cropping,noise addition, low-pass and median filtering and so on.关键词
