Abstract
We present a systematic design method for quadratic filters, and show an example for an edge detector, Our design maximizes the output signa l-to-noise ratio (SNR) constrained to detect desired signals while ign oring specified error signals such as shot noise. This filter compares favorably with Sobel and morphological detectors of similar complexit y.
