子波变换图象的熵编码标量量化蒋良成，张辉，茅一民，何振亚（东南大学无线电工程系，南京２１００１８）在使用熵编码标量量化编码子波变换图象的图象压缩技术中，为了获得线性相位ＦＩＲ滤波器，不得不放弃正交子波变换，而使用双正交子波变换。对某些信源，熵约束标量...
Entropy coding scalar quantization of wavelet transform image JIANG Liang-cheng, ZHANG Hui, MAO Yi-min, HE Zhen-ya (Department of Radio Engineering, Southeast University, Nanjing 210018) In the image compression technology using entropy coding scalar quantization coding wavelet transform image, Linear phase FIR filter, had to abandon the orthogonal wavelet transform, the use of biorthogonal wavelet transform. For some sources, the entropy-constrained scalar ...
