Region growing segmentation. In this tutorial we will learn how to use the region growing algorithm implemented in the pcl::RegionGrowing class. The purpose of the said algorithm is to merge the points that are close enough in terms of the smoothness constraint. Thereby, the output of this algorithm is the set of clusters, where each cluster is a set of points that are considered to be a part of the same smooth surface.

Region growing - Wikipedia
https://en.wikipedia.org/wiki/Region_growing
Region growing is a simple region-based image segmentation method. It is also classified as a pixel-based image segmentation method since it involves the selection of initial seed points. 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 clusteringalgorithms. A general discussion of the region growing algorit…
