Detailed Description

compute the bisector function of a binary image

Usage: bisector dist.pgm mask.pgm out.pgm

Description:

The bisector function is computed for the points which are non-null in the binary image mask.pgm , from the exact quadratic euclidean distance map found in dist.pgm .

Warning:

If the image dist.pgm is not an exact quadratic euclidean distance map, then the result of this operator will make no sense.
