摘要：
We study general zero-crossing-based discontinuity detectors in two dimensions, which include Marr-Hildreth, residual, difference of Gaussians, and other detectors as special cases. We provide mathematical justification for this class of detectors. Among them, we derive an optimal one, which maximizes the signal-to-noise ratio. Preliminary experimental results on real images are reported.
