Detailed Description
@brief The base class for all the region grower class.
The Region Grow algorithm assumes that a target area is a connected area.
The algorithm starts from some initial target pixels (seeds),
and then attempts to grow out the whole target region based on some criteria
This base class codes up the region grow algorithm process for extracting the target region:
1. Initialize from a single pixel or a binary mask, whose pixels will be marked as target pixels
and as "seed" (term for the accepted target pixels whose neighbor pixels have not been examined)
2. while (seed list is not empty):
2.1 pop out a seed and check its neighborhood pixels.
2.2 for each neighbor, if it is out of bounadry, or already been marked as accepted or discarded, then pass
2.3 for each neighbor, if it can pass some criteria, then mark as accepted and add to the seed list
else mark as discarded and continue Constructor & Destructor Documentation
