Abstract

Edge extraction is an important pre-processing operation in image processing and pattern recognition in machine vision. For example, coherent optical image processing for edge detection can be performed in a standard 4-f system with proper pupil designs. The possibility of pre-processing using digital holography for 3D image edge extraction is intriguing. In this talk, we will review some of the edge detection techniques used in single-pixel digital holography called optical scanning holography (OSH). OSH is a two-pupil system and different edge detection schemes through the different combinations of pupils are discussed.
