摘要
传统的边缘检测算子是基于梯度函数的边缘检测算法,没有考虑图像特征的多样性.针对传统算法的不足,结合边缘方向能量模型和谱聚类算法,提出了一个新的边缘检测算法.利用航空影像进行验证,实验结果表明该方法检测影像边缘的结果比较理想.
Traditional edge detection methods based on Brightness Gradient fail to take the fact of several image features into account.In view of the traditional arithmetic insufficiency,this paper uses oriented energy model and spectral clustering,proposes a novel edge detection algorithm.By using aerial image,the experimental results show that this edge detection method can gain ideal results.
