Multiwavelet-based Image Watermarking Using Coding Scheme
碩士 === 清雲科技大學 === 電機工程所 === 99 === A wavelet-based watermarking process utilizing improved channel coding techniques is proposed. The image is decomposed by discrete wavelet transform (DWT) and the watermarks are embedded in sub-blocks of the third level by adjusting the coefficients. After data per...
