How can I divide a large imgage with small ones with overlap and resample them again?

Hello,

Thank you in advance, I am a new programmer in matlab.

I have to process big images and the code I need to work with is not able to operate with them.

So my idea was divide the image into smaller ones with an overlap (as I always have to take care about the boders), treat them and then merge them again for having again a unique image. I've tried with blockproc or mat2cell but I always have errors.

Maybe there is another way to do this, like running windows or something similar.

Any suggestion is welcome!

Thank you!
