一种提高光学目标识别速度的多通道方案

Multi channel approach for improving the speed of optical target recognition

本文以形态学击中击不中变换作为理论依据，以非相干光相关器作为光学实现硬件，推导了在非共轴相关条件下相关点位置的计算公式。基于系统的平移不变性，在无需增加任何分束器的情况下实现了多通道并行处理方案，不仅充分利用了空间光调制器的工作幅面，而且大大提高了识别速度，体现了光学方法的并行性和快速性。文中给出了用四通道结构，以正面人脸图像作为测试对象的实验结果。

In this paper, a multi channel optical target recognition approach based on morphological hit or miss transformation and incoherent correlator is presented. It effectively improves the recognition speed compared to previous single channel approach and shows the parallelism and fastness of optical methods is target recognition area. A four channel structure is constructed and the experimental results in which frontal images of human faces are used as the subjects are given.
