A Fast Sub-pixel Edge Detection Algorithm

XU Zhong-y

Open publisher page 2 citations

Abstract

A sub-pixel edge detection algorithm based on orthogonal polynomial fitting was proposed, and the direct expression to calculate edge points was given.The algorithm has higher detection accuracy and uses less detection time.However,previous sub-pixel edge detection algorithms can not solve these two problems simultaneously and effectively.Compared with Gauss and spatial moment algorithms,this algorithm can obtain the sub-pixel level edge position fast and accurately.
