【摘要】 提出了采用参考图像功率谱为阈值的自适应阈值二值化联合变换相关器 ( BJTC)的方法。和传统的联合变换相关器结果比较 ,自适应阈值法对于输出的相关峰值、信噪比等主要参数都有明显提高。对这种方法进行了理论分析和计算机模拟 ,并给出了光学实验结果 ,为自适应阈值二值化联合变换相关器的实用化奠定了基础。更多还原

【Abstract】 In this paper, a new adaptive binarization thresholding method with using the power spectrum of the reference image on optical joint correlator was proposed. The performance of the adaptive binarization thresholding method has been compared with that classical optical correlator in the areas of correlation peak to and SNR (signal to noise ratio). At last, the results of the analyzing in theory, the digital simulation in computer and experiment in optic are satisfied.更多还原
