+A word about
region growing , and this implementation :
This approach to segmentation examines neighboring pixels of initial “seed points” and determines whether the pixel neighbors should be added to the region. The process is iterated on, in the same manner as general data clustering algorithms"
Basically, region growing is an
iterative method used to extract similar parts of an image. One or several points are chosen as a start. The region then grows until it is finally blocked by the
stop criteria. This criteria is generally an inside/outside region comparison (energy, size, . . .).

+Region growing is massively used in medical imaging, and object detection.
Here is an example of application in automatic Mine Hunting, which I worked with last year at
TNO.
The following method uses one seed point, defined by the user. The region grows by comparing with its neighbourhood. The chosen criteria is in this case a difference between outside pixel's intensity value and the region's mean.
The pixel with minimum intensity in the region neighbouhood is chosen to be included. The growing stops as soon as the difference is larger than a threshold.
