用C语言实现区域增长，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, regional growth is a very important image segmentation method using the C language. It refers to starting from a certain pixel, compare access pixels adjacent to the feature vectors (including gray scale, edge, texture, and other characteristics), in the pre-specified criteria, and if they are sufficiently similar to the merge as the same region, in this way similar characteristics region growing, and finally the formation of the divided image.
