On local detection of moving edges
Taejin Hwang, James J. Clark · 2002
The authors propose a detection framework with multiple velocity channels for moving edges based on a generalization of J. Canny's edge detector (1986). Finite state machines (FSMs) are set up at discrete lattice points in the image plane and operate based on the outputs of all velocity channels. The outputs of the FSMs denote whether there are edges at their corresponding positions, and their states record the edge velocities. In the temporal dimension, statistics are attached to the edges to aid in removing phantom edges.>
