An Adaptive Watermarking Technique Based on DWT Domain and FCM Algorithm
Ma Hong · Journal of Sichuan University · 2006
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.
