Abstract :
General zero-crossing-based discontinuity detectors in two dimensions, which include Marr-Hildreth (1980), residual, difference of Gaussians, and other detectors as special cases, are discussed. Mathematical justification for this class of detectors is presented. An optimal detector that maximizes the signal-to-noise ratio is derived. Preliminary experimental results for real images are reported
