区域生长算法被证实是一个有效的图像分割方法。区域生长的基本方法是从被分割对象

里作为种子区域(通常是一个或多个像素)的一个区域开始，在种子区域的相邻像素寻找与种

子像素有相同或相似性质的像素，并将这些像素合并到种子像素所在的区域中。将这些新像

素当作新的种子区域继续进行上述过程。区域生长算法主要取决于用来选择确定为种子区域

像素的标准、用来确定相邻像素的连通性类型和用来访问相邻像素的策略。-Region growing algorithms have proven to be an effective approach for image segmentation.

The basic approach of a region growing algorithm is to start from a seed region (typically one or

more pixels) that are considered to be inside the object to besegmented. The pixels neighboring

this region are evaluated to determine if they should also be considered part of the object. If

so, they are added to the region and the process continues as long as new pixels are added to

the region. Region growing algorithms vary depending on thecriteria used to decide whether a

pixel should be included in the region or not, the type connectivity used to determine neighbors,

and the strategy used to visit neighboring pixels.
