摘要 在工业现场拍摄的图像一般对比度比较低,用传统的边缘检测方法提取的边缘特征不明显。文中提出了一种基于数学形态学的多结构元算子边缘检测的方法,对弱对比度图像进行了边缘检测实验,其结果与Sobel边缘检测算子、传统形态学梯度算子相比较,表明提出的检测算子具有检测精度高,噪声不敏感等显著特点。 Based on the definition of multi direction and multiscale morphological structuring elements, an approach of image edge detection is constructed in this paper. Experiment results are obtained by applying the edge detectors on the low contrast image, which prove to be more efficient than the Sobel and traditional morphology edge detectors.
