提出一种新的采用高通滤波的二元联合变换相关器。这种相关器与一般的二元联合变换相关器的差别在于联合功率谱作二元处理之前先进行高通滤波。使用这种技术,可以产生比二元联合变换相关器更好的相关输出性能。给出对含有灰度级物体的输入景物的计算机模拟结果。

A new binary joint transform correlator (BJTC) with high pass filtering is.proposed. The difference between the proposed correlator and BJTC is that joint power spectrum is processed by using high pass filtering before applying binarization. The technique is found to yield significantly better correlation output performance than the AJTC. Comupter simulated results for input scences with gray-scale objeet are given.
