I have image of 768 by 1024 pixels, I want to perform an order statistical filter (min and max) on it by employing confilt order with a 5 by 5 window OP = colfilt(IP, [5 5], 'sliding', @min); but I got this error message "??? Error using ==> reshape To RESHAPE the number of elements must not change.
Error in ==> colfilt at 183 b(i*mb+brows,j*nb+bcols) = ..."

Don't use colfilt.
To get the local min
minImage = imerode(grayImage, ones(5));
To get the local max
maxImage = imdilate(grayImage, ones(5));
To get the local max-min
rangeImage = rangefilt(grayImage, ones(5));

The function to perform Order Statistical Filtering in the Image Processing Toolbox is ordfilt2 (R2014a). Would that be what you want?
If you already tried ordfilt2 and it didn’t do what you wanted, what was the problem?
