Black Level Uplift

Overlapping edges may appear lighter than the rest
of the image. Counteract this effect by raising black
levels in the rest of the image. The amount of uplift
required will be either x2 or x4, depending on how
many images are overlapped.
The following example shows a segment with
overlapping edges on all sides.
Unblended Region

This region is not overlapped. Black level
should be raised by the maximum overlap
occurring within the segment, therefore
should be x4.
