| 摘 要： | 本文提出了在彩色联合变换中使用光栅对彩色物体进行分通道处理的方法；讨论了实现此方法对光源、滤色片的限制，并基于此讨论结果提出了一种使用三色光栅图像编码的分通道解决方法．这种方法不但降低了对光源的限制，而且也便于取向不同的功率谱进行分通道并行处理，包括并行地使用零级功率谱进行彩色图像的仅形状相关．

| Abstract: | In this paper, we introduce a colour JTC (Joint Transform Correlator), in which grating is used for channeling, and also we discuss the restriction on the white light source and colour filter in the experiment. Based on our discussion, a new method of channeling using a three color grating for pattern coding is suggested. Because of using this new method, not only the restriction on the light source is relieved, but also the power spectrums of the coded patterns which appear in the different orientations are easy for experimental processing in parallel channeling. Besides, the zero order power spectrum also forms an important channel for shape only correlation. |
