NAME

ppmrelief - run a Laplacian relief filter on a PPM image

SYNOPSIS

ppmrelief

[ppmfile]

DESCRIPTION

This program is part of Netpbm(1).

ppmrelief reads a PPM image as input, does a Laplacian relief filter, and writes a PPM image as output.

The Laplacian relief filter is described in ’Beyond Photography’ by Holzmann, equation 3.19. It’s a sort of edge-detection.
