基于MATLAB的若干苹果边缘检测方法及其特性的对比研究

Comparative Study of Several Apple’s Edge Detection Methods and Characteristics Based on MATLAB

首先介绍了数字图像处理中边缘检测的基本原理以及常见方法。这些方法包括Sobel算子、Roberts算子、Prewitt算子、Canny算子、Kirsch算子和Gauss-Laplace算子。然后在实验室条件下,通过MATLAB编程将这些方法用于苹果边缘的检测。最后将这些方法及其特性进行系统地对比,结果表明:在当前实验室条件下Kirsch算子用于苹果边缘检测效果较好。

The basic theories and usual methods about edge detection in digital image processing firstly are introduced. The methods contained Sobel operator,Roberts operator,Prewitt operator,Canny operator,Kirsch operator and Gauss-Laplace operator. And secondly,all these methods above were used for apple’s edge detection based on MATLAB. Finally,all of them were compared as fully as possible. The results demonstrate that Kirsch operator is better than others in current laboratory condition.
