Abstract

Abstract: A novel morphological edge detection algorithm is proposed，and is applied to images edge detection.With proper structure elements，it is more efficient than conventional algorithm when applied both in noised and common images，especially in noised images.We also have compared it with other algorithms，the experiment validated the algorithm.

Key words: morphological filtering, edge detection, multi-scale

摘要： 在数学形态学基础上提出了一组新的形态学双梯度算子，把它们用于图像边缘检测，适当选取结构元素，得到了在有噪声，和没有噪声的条件下都较好的效果；并把结果与其他检测效果做了比较，实验验证了该组形态学双梯度算子的可行性和有效性。
