摘要
本文针对图像边缘检测实时性要求高的环境,提出一种快速边缘检测算法。算法通过模块搜索找到种子点并利用种子点定位初始边缘点。定义了一个8邻域延伸扇,并基于8邻域延伸扇对边缘进行搜索,降低了搜索复杂度。实验表明,新的算法在对精度影响不大的情况下,能极大地提高边缘识别的处理速度。
A fast edge detection algorithm is presented to solve the problem of high real-time edge detection. Through finding the seed points,the algorithm locates the initial edge points. Defining an 8 neighbor extends fan to reduce the detection complexity and the experiment shows the method can greatly improve the detection speed but has little influence on the accuracy.
