Abstract

Abstract

This paper presents a new edge detector using 5x5 window, which can reduce the noise effect efficiently but not increase the width of the detected edge which always happened,, in case of using 5x5 window edge detector. Besides that, in order to handle the problem that the contrast reduced in the dark region is caused by underexposure, this detector uses a auto-changeable threshold, so that it can detect the edge in regions of different grey background correctly.
