Abstract

A method for digital image processing that uses optical array logic (OAL) is presented. Parallel thresholding and digital filtering are demonstrated. OAL is a promising computational paradigm for digital optical computing based on parallel neighborhood operations for two two-dimensional binary images. In the proposed method, virtual processing elements are assumed on an image plane and a gray pixel in an original gray image is stored in each processing element. Efficient gray-image processing can be achieved by data manipulation in the virtual processing elements and in the data communication among them by using OAL. Several simulation results are presented. Finally, hardware requirements for the developed algorithms and their capabilities are discussed.

摘要

提出了一种使用光学阵列逻辑（OAL）的数字图像处理方法。展示了并行阈值处理和数字滤波。OAL是一种基于对两个二维二值图像进行并行邻域操作的数字光学计算的有前途的计算范式。在所提出的方法中，假定在图像平面上有虚拟处理元件，并且原始灰度图像中的每个灰度像素存储在每个处理元件中。通过在虚拟处理元件中进行数据操作以及利用OAL在它们之间进行数据通信，可以实现高效的灰度图像处理。给出了几个仿真结果。最后，讨论了所开发算法的硬件要求及其性能。
