摘要
Ｒｉｔｔｅｒ的图像代数定义的三种基本的图像与模板间操作可以表达多种图像变换。本文通过加权、位移和叠加等三层图像操作统一实现这三种模板操作，并设计了一个双层光电混合结构：在多重成像－阈值操作层中，采用一种空间线性光强编码方法编码输入图像，以实现两种加权计算；在相关操作层中实现图像的位移和叠加，相关结果由ＣＣＤ接收，通过电子计算机辅助处理。文中对一维图像进行了实验验证。
The three basic image-template operations, which are defined in Ritter's image algebra, can describe many image traforms. In this paper, three operations are implemented with three step of image operations including: weighting, shifting and superposition. A two-layer optoelectronic architecture is provided: in the multi-imaging-threshold layer, two kinds of weighting are done with an space linear intensity coding methods; in the correlating layer, the images are shifted and superposed. The correlatedresult is detected by a CCD, and further processed by an computer. ExperimentS on 1Dimages are demonstrated.
