Phase unwrapping algorithm based on reliability and edge detection

Abstract

A new phase unwrapping algorithm based on reliability and edge detection is presented. Since the edge is detected efficiently through edge relaxation, the unwrapping procedure is simplified within the areas embraced by edges. Penetrating edges according to reliability ensures that this method will limit the unwrapping error to local-minimum areas at worst. © 1997 Society of Photo-Optical Instrumentation Engineers.
