Paper Abstract

Optical implementation of Hough transform filter is investigated for parallel detecting two kinds of element shape. Two kinds of Hough transform are optically implemented by a two-dimensional array of computer-generated-holograms which simultaneously reconstruct two point spread functions corresponding to lines and circles. A novel matrix format is adopted to parameter domain in Hough transform instead of conventional orthogonal coordinate system.
