基于多结构元素的形态学边缘检测算法

本文提出了一种基于多结构元素的形态学边缘检测算法,该算法利用形态学的基本运算膨胀、腐蚀、开、闭及它们的组合,并通过构造4个不同方向的结构元素,得到图像4个方向的边缘检测结果,并将这些结果加权平均,得到最终的图像边缘。结果表明,该算法的性能优于经典的LoG算子和Canny算子,检测出的边缘平滑性好,特征清晰,而且具有一定的抗噪性。

A Morphology Algorithm of Edge-Detection Based on Multi- Structural Elements

This paper puts forward a kind of morphology algorithm of edge-detection based on muhi- slructural elements. The algorithm adapts the basic morphological operations such as dilation, erosion ,opening, closing and their combination ,builds four structure elcments to get lbur edge- detection, averages these edges to gain the final detecting result. The experiment resuhs show that the capacity of this algorithm is evidently better than classical Laplacian operator and Canny operator, further more, it deblured the detected edge efficiently and eliminated the influence of noise appropriately.
