A novel method for performing color image recognition by the use of the coherent joint-transform correlator is introduced. The input plane of the proposed method is a spatial rearrangement of the separation into color channels of both the color input scene and the color target. This input plane is gray scaled and monochromatic, thus it can be displayed by the use of amplitude spatial light modulators to achieve real-time operation. The system provides a single output-plane result of the optical coherent addition of the separate channels' correlation outputs. At the output plane no electronic postprocessing is needed, and the detection decision is achieved simply by the application of threshold detection. Experimental results and computer simulations are presented to demonstrate the abilities of this system.
介绍了一种利用相干联合变换相关器进行彩色图像识别的新方法。该方法的输入平面是将彩色输入场景和彩色目标的颜色通道分离进行空间重排得到的。这个输入平面是灰度的且为单色，因此可以通过使用幅度空间光调制器来显示以实现实时操作。该系统提供了各个通道相关输出的光学相干相加的单一输出平面结果。在输出平面无需电子后处理，通过应用阈值检测即可简单地做出检测决策。给出了实验结果和计算机模拟以证明该系统的能力。
