We explain that a holographic filter of the generalized Hough transform can be easily obtained by the use of multiplexing techniques in hologram recording. To show the feasibility of our approach experimentally, we recorded the Hough transform filter of both line and circle parameterizations by combined use of rotational and angle multiplexing. Experimental results on the Hough transform for a few input patterns are presented.
