融合阈值法和边缘提取的图像分割算法

Image Segmentation Algorithm of Combined Threshold Segmentation and Edge Extraction

针对阈值法分割目标区域不完整和边缘提取断续边缘多的问题,提出了一种融合阈值法分割和多尺度边缘提取的图像分割算法。该算法充分利用阈值分割提供的目标区域信息和边缘提取给出的边缘信息,采用基于区域生长的最大轮廓法连接断续边缘,填充目标孔洞,完成目标分割。利用Matlab平台对该算法进行了验证,结果表明:该算法能有效分割出目标完整轮廓。

Aiming at the problem that the target area is incomplete processed by threshold segmentation and lots of intermittent edges retain after edge extraction,an image segmentation algorithm is proposed which combines the threshold segmentation and multi-scale edge extraction.The algorithm makes the best of the information of target area got from threshold segmentation and edge information provided by edge extraction,and then uses the maximum profile method based on region growing to connect the intermittent edge for filling target hole and completing target segmentation.The validity of this algorithm is proved by using Matlab,and the complete target profile can be extracted effectively.
