区域生长，图像的分割，种子点选取流程。图像分割是将图像分割成若干特定的、唯一的区域，并呈现出感兴趣的目标的技术和过程。它是从图像处理到图像分析的关键步骤。现有的图像分割方法分为基于阈值的分割、基于区域的分割、基于边缘的分割和基于特定理论的分割。自1998年以来，研究人员对原有的图像分割方法进行了改进，并将其他学科的一些新理论和新方法应用到图像分割中，提出了一些新的分割方法。图像分割后提取的目标可用于图像语义识别、图像检索等。
English Description：
Region growing, image segmentation, seed point selection process. Image segmentation is the technology and process of segmenting an image into several specific and unique regions and presenting the interested objects. It is a key step from image processing to image analysis. The existing image segmentation methods are divided into threshold based segmentation, region based segmentation, edge based segmentation and specific theory based segmentation. Since 1998, researchers have improved the original image segmentation methods, and applied some new theories and methods of other disciplines to image segmentation, and proposed some new segmentation methods. The object extracted after image segmentation can be used for image semantic recognition, image retrieval and so on
