摘要
实验过程中发现,输入图像的形状特征对联合变换相关器的相关峰的分布具有较大的影响。通过采用两个相同的矩形作为目标图像和参考图像,改变矩形的长宽比,获得了一组在垂直方向和水平方向分布变化较大的相关输出,并分析了产生的原因。
The experimental data shows that the form character of input picture influences the distribution of JTC correlation peak. A group of correlation output are obtained which is different in the vertical direction and horizon direction by changing the length-width ratio of two same rectangles as the target picture and reference picture. At last, the cause to the phenomena is analyzed.
