The boxFilter only applies to the NL-Means weights (part of computing the patch-wise distances can be reduced to a box-filter), and the corresponding data window contains enough padding so that it filters across tile boundaries. When I implemented it, I verified the tiled version against the un-tiled ground truth and the results are identical.
The bug applies to the regression and depth feature. The regression in this code sometimes overfits and carries over some residual noise, which the original EGSR version did not. Additionally, the depth feature causes odd banding artifacts (they look like concentric circles). I'm actually at a loss why that happens - they shouldn't behave like that, but somewhere my regression/weight code is doing something very odd.
