    Apply local contrast enhancement to and ImageProcessor. The method performs best when you adjust the ImageProcessors min and max range such that a region of interest in the image has optimal contrast and spans the full range.
    
    Parameters:
    
    ip -
    
    brx - block width
    
    bry - block height
    
    stds - in case that the contrast is to be stretched, how many STDs wide should it be
    
    cent - local contrast range at the estimated mean (the original mean is at (max-min)/2), that is mean is mapped to min+(max-min)/2.
    
    stret - stretch contrast such that mean-stds*STD is mapped to min and mean+stds*STD is mapped to max (if cent is true) otherwise only the scaling is performed such that max-min = 2*stds*STD
