regiongrowing_meanregiongrowing_meanRegiongrowingMeanRegiongrowingMeanRegiongrowingMean performs a regiongrowing using the mean
gray values of a region, starting from points given by
StartRowsStartRowsStartRowsStartRowsstartRows and StartColumnsStartColumnsStartColumnsStartColumnsstartColumns. At any point in
the process the mean gray value of the current region is calculated.
Gray values at the boundary of the region are added to the region if
they differ from the current mean by less than ToleranceToleranceToleranceTolerancetolerance.
Regions smaller than MinSizeMinSizeMinSizeMinSizeminSize are suppressed.
If no starting points are given (empty tuples), the expansion
process starts at the upper leftmost point, and is continued with
the first unprocessed point after a region has been created.
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Automatically parallelized on tuple level.

regiongrowing_meanregiongrowing_meanRegiongrowingMeanRegiongrowingMeanRegiongrowingMean returns 2 (H_MSG_TRUE) if all parameters are
correct. The behavior with respect to the input images and output
regions can be determined by setting the values of the flags
'no_object_result'"no_object_result""no_object_result""no_object_result""no_object_result", 'empty_region_result'"empty_region_result""empty_region_result""empty_region_result""empty_region_result", and
