立体图像对编码的MATLAB实现程序。包含了匹配跟小波变换2种算法

% Matlab implementation of SPIHT (without Arithmatic coding stage)
%
% The function in this toolbox are listed as follow:
%
% func_SPIHT_Main -- Main function
%
% func_SPIHT_Eec -- Encoder
%
% func_SPIHT_Dec -- Decoder
%
% func_DWT -- Wavelet decomposition
%
% func_InvDWT -- Inverse wavelet decomposition
%
% func_ReadRaw -- Read a RAW format gray scale image from disk
%
