A method of extracting image edge feature based on phase shift

摘要

This paper proposed a new method of image edge detection based on the phase shift at the edge point. Two operators which are called odd operator and even operator, convolved respectively with the image. Phase congruency point can be determined by the convolution result. Then, the edge point and edge type can be obtained according to the phase congruency series, which is consisted by phase congruency points. The method has high anti-noise property, and simple calculation.
