CARTOON: A Biologically Motivated Edge Detection Algorithm

Abstract

Caricatures demonstrate that only a few significant "edges" need to be captured to convey the meaning of a complex pattern of image intensities. The most important of these "edges" are image intensity changes arising from surface discontinuities or occluding boundaries. The CARTOON algorithm is an attempt to locate these special intensity changes using a modification of the zero-crossing coincidence scheme suggested by Marr and Hildreth (1980).
