一种改进的Canny边缘检测算法
An improved Canny edge detection algorithm
摘要
Abstract
This article puts forward an improved Canny operator edge detection algorithm . This algorithm uses DWT decomposi-tion and weighted reconstruction to smooth and filter , uses Otsu threshold method ( the largest between-cluster variance method ) to seek the best delay threshold and seek gradient method in 3 × 3 neighborhood . Experimental results show that the algorithm can preserve more edge when better suppress noises , so that the detected edge of the image is more accurate and abundant .关键词
