一个图像小波数字水印的matlab代码,利用小波变换，在DC分量上实现自适应编码-An image digital watermarking wavelet matlab code, the use of wavelet transform, the DC component on the realization of adaptive coding

Choice of Wavelets for Image Compression In wavelet-based image coding the choice of wavelets is crucial and determines the coding performance. Current techniques use computationally intensive search procedures to find the optimal basis (type,
