childmat.asv

EZW的matlab程序 基于小波变换对图像进行压缩编码的研究

function chMat=childMat(Mat,chRows,chCols)
global row col
[row,col]=size(Mat);
chPoint=treeMat(chRows,chCols);
chMat=[];
[mRows,mCols]=size(chPoint);
for iRows=1:mRows
    chMat=[chMat;chPoint(iRows,1),chPoint(iRows,2),Mat(chPoint(iRows,1),chPoint(iRows,2))];
