灰值数学形态学的二值算法及其光学实现

Binary Algorithms of Grayscale Mathematical Morphology and Its Optical Implementation

在灰值数学形态学的阴影算法的基础上，提出了采用表面点集代替阴影来代表灰值结构核的改进算法，大大降低了二值邻城互连的数量。光学实现采用一个光学非相干相关器与阈值器件结合的二值数学形态学系统，并设计了一种数字空间编码技术使这二维系统能实现算法要求的有限三维操作。

his peper presents an improving algorithm of grayscale morphological operations based on the definition by umbra. The main idea of the algorithm is to represent grayscale structure element by its top-surface-set, iusted of its umbra. This greatly reduces the binary neibourhood connection numbers. An optical binary morphological architecture of an incoherent correlator with threshold device is used for optical implementation, while spatial digital coding method is used to extend the 2D system to limited 3D operations.
