Hi, I don't think the region growing is exposed in an application. You can try to look into applications :

Hi, I'm looking for a way to delineate tree canopies from hight resolution raster. Input data include RGB and hyperspectral rasters and point shapefile with points represeting individual tree crown center. Desired output is a polygon vector containing a individual tree crown limits, raster output also ok if it can be used for vectorization.As I understand, this task can be solved by using "region growing" segmentation. OTB Software Guide [0] and OTB API docs [1] reference this algorithm, but I can find it among command-line tools. Is it available only via API? Maybe I can also use some other algorithms? Sample of the desired output attached. Blue dots are tree top points, red polygons represent each tree canopy.
