图像分割在实际中已得到广泛的应用，例如在工业自动化，在线产品检验，生产程控，文件图像处理，遥感和生物医学图像分析，保安监视，以及军事、体育、农业工程等方面。概括来说，在各种图像应用中，只要需对图像目标进行提取、测量等都离不开图像分割，分割的准确性直接影响后续任务的有效性，因此图像分割具有十分重要的意义。-Image segmentation has been widely in practical applications, such as industrial automation, on-line product testing, production and program control, document image processing, remote sensing and biomedical image analysis, security monitoring, as well as military, sports, agriculture and engineering. In general, in a variety of image applications, as long as the target images need to extract, measure and so can not do without image segmentation directly affects the accuracy of the effectiveness of follow-up to the task, so segmentation is of great significance.
