基于Soft形态学的图像去噪边缘检测

Edge Detection Method for Denoising Based on Soft Morphology

基于形态学的图像处理效果取决于运算性质和结构元素,为了能够更好地抑制图像的噪声并且提取边缘信息,提出了一种基于柔性形态学的图像去噪和边缘检测方法。该方法使用多结构元复合滤波与双梯度多路合成相结合,柔性的多结构元复合滤波能够有效去除图像噪声,双梯度多路合成可以提高图像边缘的检出率,不仅抑制图像的噪声,而且提取出的图像边缘更清晰完整。实验结果表明,该方法在抑制噪声和边缘检测方面要比传统算法有较好的效果。

The image processing effect based on morphology is depending on the operation and the structural element.To suppress noise of image and withdraws the edge information.A method which uses multi-element composite structure with dual gradient filter and multiple synthesis methods based on soft morphology was presented.Flexible multi-element composite structure could effectively remove the image noise filtering,and dual-gradient multiplex could improve the detection rate of the image edge.The experimental results show that the method is better than traditional algorithms in suppressing noise and edge detection.
