实现图像的无损压缩
该程序主要实现图像的无损压缩,具体算法包括:
(1)整数小波变换+SPIHT无损压缩
其中整数小波可以采用JPEG2000提供的5-3小波,也可以采用S+P变换,本程序均已给出。
(2)DPCM+算术编码
DPCM采用的是JPEG中采用的方法;
(3)JPEG-LS标准
JPEG-LS的无损压缩性能非常好,超过JPEG2000。(The program mainly realize lossless image compression, the specific algorithm include: (1) integer wavelet transform SPIHT Integer Wavelet lossless compression which can be used to provide the 5-3 wavelet JPEG2000, can also adopt the S P transform, the procedures are given. (2) DPCM arithmetic coding DPCM is used in JPEG methodology (3) JPEG-LS standard JPEG-LS lossless compression of very good performance, more than JPEG2000.)
