Universally analyzed and discussed in this paper is the visualization of inhomogeneous phase distribution of phase objects with spatial zero frequency filtering and knife edgefiltering method.
In the paper, a way of smooth filtering first, then detect edge using fuzzy sets in complex scene image is provided.
本文提出一种首先进行平滑滤波,然后检测模糊边缘的方法来进行复杂景物图像边缘检测。

In this paper, a direct edge detection method which combines filtering and detecting is introduced. The edge detection is based on adaptive stack filter.
