resize_jpg.m

基于小波的人脸识别算法的matlab实现

function resize_jpg(filename,dirname,m,n)

fname=strcat(dirname,'\',filename);
X=imread(fname,'jpg');

Z=imresize(X,[m,n],'bicubic');

savefile =strcat(dirname,'\after\',filename);

% savefile =strcat(dirname,'\',strrep(filename,'1_mult',''));
imwrite(Z,savefile,'jpg');
