    Non-maximal suppression for features/corners Non maxima suppression and thresholding for points generated by a feature or corner detector. Note: An issue with integer valued images is that if there are multiple pixels all with the same value within distance 2*radius of each other then they will all be marked as local maxima.

    Parameters:
    
    destImg - Optional image. If this is supplied, the thresholded corners are overlayed on this image. This can be useful for parameter tuning
    
    srcImg - Corner strength image
    
    VOIs -
    
    radius - Radius of the region considered in non-maximal suppression. Typical values to use might be 1-3 pixels.
