Optical implementation of the generalized Hough transform by use of multiplexed holograms
Dong-Hak Shin · Optical Engineering · 2000
We explain that a holographic filter of the generalized Hough transform can be easily obtained using multiplexing techniques in hologram recording. To show the feasibility of our approach experimentally, we record the Hough transform filter of both line and circle parameterizations by combined use of rotational and angle multiplexing. Preliminary experimental results on the Hough transform for a few input patterns are presented.
