matlab环境的小波压缩算法，给予dwt的心电图压缩，滤去了高频分量，具有较高的压缩比率-matlab environment wavelet compression algorithm, giving dwt ECG compression, filter the high frequency components with high compression ratio

a new hybrid transform coding methodology for lossy image compression that integrates discrete wavelet transform, discrete cosine Transform and singular value decomposition methods is proposed. The proposed system has enhancements in both the com
