描述
regiongrowing_meanregiongrowing_meanRegiongrowingMeanRegiongrowingMeanRegiongrowingMeanregiongrowing_mean performs a regiongrowing using the mean
gray values of a region, starting from points given by
StartRowsStartRowsStartRowsStartRowsstartRowsstart_rows and StartColumnsStartColumnsStartColumnsStartColumnsstartColumnsstart_columns. 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 ToleranceToleranceToleranceTolerancetolerancetolerance.
Regions smaller than MinSizeMinSizeMinSizeMinSizeminSizemin_size 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.
