Optical parallel image skeletonization using contentaddressable memory-based symbolic substitution.
In this paper, two optical image skeletonization algorithms are introduced. In both algorithms, the matching between an input and a set of precalculated parallel check patterns is performed. Based on the matching results, multistage symbolic substitution operations are incorporated. For an optical implementation, an optical hologram-based content-addressable memory technique is employed. The corresponding optical architecture as well as character skeletonization examples are presented.
