A Watermarking Method Based On Maximum Distance Wavelet Tree Quantization
碩士 === 輔仁大學 === 資訊工程學系 === 94 === This thesis proposes a blind watermarking algorithm based on wavelet tree quantization. The wavelet coefficients of the host image are grouped into what we term “ selection trees ” which are created by using the method of maximum distance in scan order of the wavele...
