DETECTING EDGES USING AN ANALOG ELECTROOPTIC DEVICE

C. J. Vianna, E. A. de Souza

Abstract


We characterized an analog Self-Electrooptic Effect Device with five photodiodes as an edge detector by the use of a step edge image as input. The device extracts edges by finding the zero-crossing points in the second order derivative of the input image.
