Stitching rejection voting mechanism. The diagram shows the case of how the voting mechanism prevents incorrectly stitching two cells stacked on top of each other in the Z-direction. Left: An example of “splitting” scenario that would have been matched by the OT formulation. The blue pixel (middle) will vote to reject stitching due to different cell labels in the corresponding index z & \(z+1\) in the YZ-masks (right)
