Target Location Based on Double-edge Detection

doi:10.3969/j.issn.1006-2475.2016.08.012

Abstract

Abstract: In order to improve the accuracy of target location, based on the traditional difference of Gaussian edge detection and Sobel operator edge detection, this paper puts forward a double edge detection algorithm which combines the two. We use the difference of Gaussian to replace the Gaussian smoothing in image preprocessing, choose better results of difference of Gaussian parameters, use Sobel edge detection after the difference of Gaussian process, and find the target location. The experimental results show that combining difference of Gaussian with Sobel operator do not increase much running time overhead, and have better detection result than the Sobel test alone.

Key words: double-edge detection, difference of Gaussian (DoG), Sobel operator, target location, target detection
