There are lots of options for this:
You might need to define smaller blocks in your image and apply it locally depending on your requirements

try dividing your image into smaller regions and apply your algorithm on each region

I don't. I see no reason why scaling an image would require doing it region by region. Nothing has been said by the original poster that would require that. And since mat2gray does exactly the operation they requested, I'm not sure why they're not following my answer.

Simply use mat2gray().
Or, if you want to scale to something other than min-to-0 and max-to-255 you can use imadjust.
