Resizing multiple images using MATLAB

Posted by : Mukunthan GJ Saturday 23 March 2013

Get all the image files that are need to be re sized in matlab current directory and run this code

dirData = dir('*.jpg');

fileNames = {dirData.name};

for iFile = 1:numel(fileNames)

newName = sprintf('%1d.jpg',iFile);

movefile(fileNames{iFile},newName);

end

After renaming the files (by running above program ) run this code

q=1;

p=1;

for i=1:10

oq=imread(strcat(num2str(q),'.jpg'));

odprz=imresize(oq,[150 150]); %# specify your size here

imwrite(odprz,strcat(num2str(p),'.png'));

q=q+1;

p=p+1;

end

collect only .png format files.That files are re-sized files.
