Selective edge detection based on harmonic oscillator wave functions

This paper describes a set of edge detectors, each of which has selective responses to each edge pattern contained in an input signal. Quantum-Mechanical Harmonic Oscillator Wave Functions are applied to extracting a variety of edge information indispensable to identifying each edge pattern. Information, obtained over the scale space, is also integrated so that edges can be detected even if an input signal is distorted with noise.
