Similarity measure is usually used to study the similar degree between multisource data, which is the basis of pattern recognition on spatial data.
相似性度量是用于研究多源数据之间相似程度的，是对空间数据进行模式识别的基础。
In this paper, two methods of realizing optical pattern recognition, spatial matched filter correlation and joint transform correlation (JTC), were discussed first with the emphasis on the JTC.
本文首先论述了实现光学模式识别的两种方案，空间匹配滤波相关识别和联合变换相关识别的原理和技术。
The fractional Fourier transform contains the spatial information and the spatial-frequency information simultaneously. The fractional correlation can be used to optical pattern recognition too.
分数傅里叶变换同时包含了空间域和空间频率域信息，分数相关也可以用于光学图样识别。
