Depending on the seed point choice, meaningful gray values are excluded by the automatically derived lower threshold setting (in the upwards-growth case).

More specifically, from the seedpoint neighborhood, the mean gray value is chosen as lower threshold for 3D region growing. Thus, gray value variance is not taken into account, leading to an excluding behaviour of the subsequent region growing.

Lower threshold is set to one standard deviation below mean gray value for the upwards growth case, in order to fix the issue.

Adjust lower threshold by neighborhood gray value standard deviation. In addition, replace hard coded out-of-bounds value by according numeric trait bounds.
