I note that it says [here](https://docs.nvidia.com/cuda/npp/group __image__ filter __compresssed__ marker __labels__ info.html):

> “Note that while the bounding box is relatively accurate occasionally a few contour pixels may extend beyond the bounding box limits.”

I’m not that familiar with what the algorithm is doing, but its possible there may be some variability run-to-run. You’re welcome to [file a bug](https://forums.developer.nvidia.com/t/how-to-report-a-bug/67911) if you wish.
