基于DWT域的数字水印技术，子带编码隐写程序-DWT domain based on digital watermarking technology, subband coding steganography program

Wavelet Subband coding for speaker recognition The fn will calculated subband energes as given in the att tech paper of ruhi sarikaya and others. the fn also calculates the DCT part. using this fn and other algo for pattern classification(VQ,GMM

EZW (Embedded Zerotrees of Wavelet Transforms) is a lossy image compression algorithm. At low bit rates (i.e. high compression ratios) most of the coefficients produced by a subband transform (such as the wavelet transform) will be zero, or very clos

子带编码程序，使用Daubechies（5,3) filter bank，自带降采样及升采样子程序-The subband coding procedures, using Daubechies (5,3) filter bank comes downsampling and upsampling subroutine
