| 摘 要： | 介绍一种用于提取目标图像和背景图像都比较简单的图像中的阶跃型边缘算法。把二值化图像中的像素点分为4类:背景点、目标体点、边缘点、噪声点;算法实现过程如下:首先对图像进行二值化处理,然后对二值图像中的目标体的边缘像素点进行跟踪,找出目标体的边缘曲线。试验表明:该算法实现简单、处理快速、抗噪性好。

| Abstract: | An algorithm for edge detection based on pixel types is presented in this paper. This algorithm is used to detect step edge in image where target image and background image are simple. The pixels in binary image are defined as four types: background pixel, target pixel, edge pixel and noisy pixel. The algorithm flow is as follows: first, image is binarized, then, the target edge is tracked by detecting edge pixel in binary image. The experiment shows that the algorithm is simple, fast and noise - standing. |
