摘要
在联合变换相关识别系统中,应用复合光栅滤波器对输入目标图像和参考图像进行微分预处理,从而突出了图像边缘信息.理论分析和实验结果表明,该方法能够抑制低频成分,改善相关输出信号的性能,提高系统的相关识别能力.
The joint transform correlation is a chief method of optical image recognition, the joint transform correlation system with a composite grating filter achieving differential pretreatment of input object image and reference image is proposed. The image edge information is extruded. The result of experiment shows that the property of correlating output signal and the joint correlation recognition ability is improved by this system.
