首先在具有明显边缘特征的图像序列中，提取图像强边缘块的直方图，然后，利用时域多分辨算法，比较不同帧之间的图像差异。

Firstly, the histogram is computed from the strong edge blocks in the image sequences. Then, different images are compared by algorithm of multi-resolution steps.

利用标量波动衍射理论进行了数值模拟，结果表明，该设计能明显降低系统像差，改变了传统设计方法在大通道数情况下像差过大、边缘通道性能劣化等问题。

Numerical simulation is carried out by means of scalar fluctuation and diffraction theory. The simulation results show that the design obviously lowers system aberration, solves the prob…
