Abstract

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

회전다중 홀로그램을 이용하여 일반화된 Hough 변환 필터를 광학적으로 제작할 수 있음을 설명하였다. 제안된 방법의 타당성을 실험적으로 보이기 위해 선소와 원을 동시에 검출하는 필터를 회전다중과 각다중을 사용하여 제작하였다. 몇몇 패턴에 대한 Hough 변환의 기초 실험 결과를 보고한다.
