OPTICAL GRAY SCALE IMAGE MATCHING BASED ON SIMILITUDE MEASUREMENT

利用非相干光相关操作处理和空间移位编码方法，实现了基于相似性度量的灰阶图像匹配处理．针对不同程度的噪声干扰情况，分析了空间移位编码方法中字长的选择问题，提高了识别的抗畸变能力，给出了基于非相干相关系统的实验示例．

The problem of gray scale image matching based on similitude measurement was discussed. Using an incoherent optical correlator and a shift encoding method, the processing of gray sclae image matching based on similitude measurement was realized. The selection of the length of shift encoding for different distortion in gray level object recognition was analyzed, The optical experimental results were given.
