区域生长是一种很重要的图像分割方法。它是指从某个像素出发，比较相邻接像素的特征向量(包括灰度、边缘、纹理等特征)，在预先指定的准则下，若它们足够相似则作为同一区域合并，以此方式使相似特征的区域不断增长，最后形成分割图像。-Regional growth is a very important image segmentation method. It is starting from a pixel comparison to neighboring connected pixel feature vectors (including gray level, edge, texture and other characteristics), pre-specified criteria, if they are sufficiently similar to be combined as the same region, in this way so that similar the characteristics of the region growing, and finally the formation of the segmented image.
