Abstract

Existing edge detection algorithms have the problem of that poor directionality and low definition. In response to this phenomenon, this paper put forward a directionality edge detection algorithm using layered processing. This algorithm by analyzing wavelet decomposition directional characteristics of high frequency sub-bands. And introduction of a direction factor in traditional edge detection algorithm which realize edge detection of multi-directional detection. In the process of edge detection, article algorithm reprocessing the weak edge signal so that it can better protection of the edge signal. This algorithm compared with the existing edge detection algorithm, this algorithm with the better performance of the fine image structure and object Edge.
