摘要
在图像处理与分析领域,边缘检测是一个重要的研究内容。本文将多尺度顺序连接算法(Multiresolution Sequential Edge Linking,MSEL)应用于乳腺边缘检测,采用金字塔结构分解图像,用低分辨率子图上的全局边缘信息指导高分辨率子图上的顺序边缘搜索,从而降低噪声干扰,减少了伪边缘,提高边缘检测的准确性。实验表明,多尺度顺序边缘连接检测算法对于乳腺放射图像的边缘检测效果有明显改善。
Edge detection Sequence Edge Linkin allows integration of glo g bal is an important area in image processing and analysis. In this paper, Muhiresolution （MSEL） is used for edge detection in mammography. The use of a image pyramid edge information contained in lower resolutions to guide the sequential search at higher resolutions. As a result, the MSEL provides for a more accurate edge by suppressing noise and reducing false edge Experiments show the improvement of edge detection effect for mammography.
