多幅图片处理的循环语句

小弟毕业设计关于视频去雾处理，将视频截取为图片后对每张图片进行处理，其中需要用到循环语句来减少工作量，但自己对循环语句不怎么会，希望哪位大大能够给予帮助，谢谢了

程序如下

block_size = 15;

infile = '1.jpg';

outfile = '1_1.jpg';

outRTfile = 'test_rawt.bmp';

outTfile = 'test_t.jpg';

outDfile = 'test_d.bmp';

showFigure = 0;

enableSoftMatting = 1;

enableBilateralFilter = 0;

I = imread(infile);

[h,w,z]=size(I);

block_size = round(h/25);

figure, imshow(I);

st=cputime;

[mI, A] = GetTMap(I, block_size);

mI=imresize(mI,[h w]);

et1=cputime - st;

disp(['Get Init Transmission Map : ' num2str(et1) ' seconds.']);

A = double(A)/255.0;

if (showFigure)

figure, imshow(mI);

end

imwrite(mI, outRTfile);

% I = double(imread('test0014-scale.jpg'));

% mI = double(imread('depth0014-scale.bmp'))/255.0;

% mI = rgb2gray(mI);

% figure, imshow(mI);

I=double(I)/255.0;

if(enableSoftMatting)

st=cputime;

softmap = GetSoftTMap(I, mI);

et2=cputime - st;

disp(['Get Soft Transmission Map : ' num2str(et2) ' seconds.']);

else

softmap = mI;

end

% softmap = double(imread(outTfile))/255.0;

% if (size(softmap,3)==3)

% softmap=rgb2gray(softmap);

% end

if(showFigure)

figure, imshow(softmap);

end

if(enableBilateralFilter)

softmap=uint8(softmap*255);

st=cputime;

softmap=bilateralFilter(uint8(softmap),3,20);

et3=cputime - st;

disp(['Bilateral Filter : ' num2str(et3) ' seconds.']);

if(showFigure)

figure, imshow(uint8(softmap));

end

softmap=double(double(softmap)/255.0);

end

imwrite(softmap, outTfile);

st=cputime;

depthMap = GetDepthMap(softmap);

et5=cputime-st;

disp(['Depth Map : ' num2str(et5) ' seconds.']);

if(showFigure)

figure, imshow(depthMap);

end

imwrite(depthMap, outDfile);

st=cputime;

result = GetRecoverMap(I, A, softmap, 0.5);

et4=cputime - st;

disp(['Recover Scene : ' num2str(et4) ' seconds.']);

figure, imshow(result);

imwrite(result, outfile);

不知道循环语句在里面怎么添加的？不胜感激啊
