基于光学异或逻辑的图像匹配

Image matching based on optical XOR logic operation

提出一种基于光学逻辑运算的图像匹配新方法.若将输入图像与每一幅存贮的图像进行光学“异或”逻辑运算,并用光电方法探测逐点逻辑运算输出光强的总和,则与最小透射光强相对应的存贮图像就是输入图像的最佳匹配.我们采用了偏振编码和多成像技术来建立该方法的光电实现系统,并做出了实验结果.

A new approach of image matching based on optical logic operation is proposed. The best match is indicated by the minimum collected transmitted light intensity resulted from optical XOR logic operations between the input image and every stored image. Polarization coding and multi- imaging technique are employed in our optoelectronic system. Experimental results are presented.
