常用的MATLAB图像压缩编码，通过matlab实现，其中包含了DM编码、变换编码（FFT和DCT）、算术编码、行程编码、JZOTch编码、线性预测编码和一个近似的NHzjZsp编码过程。本人通过MATLAB编码效率很高。 (Commonly used MATLAB image compression coding, through matlab implementation, which includes the DM coding, transform coding (FFT and DCT), arithmetic coding, run length coding, JZOTch coding, linear predictive coding and an approximate NHzjZsp encoding process. I have a high coding efficiency by MATLAB. )
