I want a MATLAB code that will resize a given image into 25x25 image using multiple images from a folder

I have total 649 images that i want to resized into 25 x 25 one shot. Is it even possible or i have to specifically select an image and resize it.

If you have the Image Processing Toolbox then

doc imresize

should work fine. Use a loop if you want to do it for 649 images.

See the FAQ:

http://matlab.wikia.com/wiki/FAQ#How_can_I_process_a_sequence_of_files.3F

and use one of the chunks of code there to process a sequence of images.

Inside the loop put a call to imresize

resizedImage = imresize(thisImage, [25, 25]);
imwrite(resizedImage, outputFileName);
