区域生长法实现图像分割

区域生长的基本思想是将具有相似性质的像素集合起来构成区域。具体是先对每个需要分割的区域找一个种子像素作为生长的起点，然后将种子像素周围领域中与种子像素相同或相似性质的像素（根据某种事先确定生长或相似准则来判定）合并到种子像素所在的区域中。将这些新像素当做新的种子像素继续进行上面的过程，直到再没有满足条件的像素可被包括进来，这样，一个区域就长成了。-The basic idea of ​ ​ the pixels to achieve image segmentation region growing region growing method is of a similar nature together constitute the area. In particular to find a seed pixel for each area divided as a starting point needs to grow, and then the areas surrounding the seed pixels with the same or similar nature seed pixel pixel (according to some pre-determined criteria to determine growth or similar) into regional seed pixel is located. These new pixel as a new seed pixels above process continues until no longer meet the conditions of the pixels may be included, so that it grew into an area.
