【摘要】 利用人类视觉系统(HVS)的掩蔽效应和小波多分辨率分析的特点,作者提出了一种通过在图象的小波域的细节部分进行模糊聚类来寻找适合嵌入水印的位置,再用隶属度作为嵌入强度来嵌入水印的新的数字水印嵌入算法.实验表明该方法能在保持图象质量的前提下提高水印的鲁棒性.更多还原

【Abstract】 An adaptive digital watermarking technique based on discrete wavelet transform(DWT) domain is proposed to classify each individual detail images into two blocks,one is appropriate for embedding watermark,the other is inappropriate,by applying fuzzy c-means clustering(FCM) algorithm based on hunman visual system.And the cluster result is used as the strength of watermarking.Experiment results show the technique is more imperceptive and more robust than some watermarking algorithms based on DWT.更多还原
