WebThe maximum filter replaces each pixel value of a Digital Image with the maximum value (i.e., the value of the brightest pixel) of its neighbourhood pixel window. It is the opposite of what the minimum filter does to an Image. Applying the maximum filter removes the negative outlier noise present in a Digital Image.

There is only one maximum at [99,99]. A sliding window would always find a local maximum in the lower right corner. Your method would basically return almost every pixel as a local maximum. – Ben. is bison meat kosher
