Hello.

I have a folder of 20 images that I need to shrink down to the size of the smallest image (smallest of those 20 in the folder). I am not allowed to to use "imresize" or "imcrop" and I am having a lot of trouble with it. The smallest image is 127 x 129. Please help!

Thank you!

How about using interp2?

Hi,

You may try implementing some image resampling techniques. The same algorithm can be used for shrinking as well as enlarging an image by using proper scale factors and pixel locations. A quick search gave me the following useful links
