RegionGrowing
快速的2D/3D区域生长算法,通过对邻近像素进行优先级排队进行加速,效果优于matlab本身的区域生长算法(Native Matlab implementations of region growing algorithms are usually quite slow, especially for 3D input data. This submission is a mex implementation of a 3D/2D region growing algorithm. The region growing process is further accellereated by using priority queues for the neighbourhood pixels.)
