Abstract

This paper introduces an edge detection algorithm based on directional wavelet transform.describes the theory of directional wavelet transform and the edge detection algorithm based on it

compares the effect in edge detection between traditional wavelet transform

Canny Operator and directional wavelet transform.With the experimental results

directional wavelet transforms can better reflect the edge information of images because it better corresponds to the image characteristics of direction and texture

it has a certain degree of improvement on traditional wavelet transform and Canny Operator.
