Abstract

We present a method to extract edges using zero-crossing feature and contour measure. This method differs markedly from previous ones, since it provided a means of quantitative analysis to detect zero-crossing. There are two main steps in this method. Firstly, the edge intensity was obtained through the value of contour measure. Secondly, the actual edges are identified according to the edges intensity. A series of experiments are performed to test the algorithm proposed, which show that the edges is extracted more accurately and completely.
