A simple image segmentation method. The segmented region grows from a
seed point by comparing neighbor pixels/voxels.
If a neighbor pixel/voxel is smaller then the specified threshold value it becomes a
part of the region.
The growing algorithm is written in C because the matlab implementations are rather
slow especially for big images or volumes.
