Consistency Checker Motion Boundaries

[pgalatic]

Hi, I wanted to know more about the decision to have motion boundaries be described as "certain" (MOTION_BOUNDARIE_VALUE = 255) in the consistency checker, as in the associated paper as well as your previous work from 2016, you describe masking out motion boundaries as uncertain.

I ran consistencyChecker with MOTION_BOUNDARIE_VALUE = 0 and got very different results on a sample operation; naturally, the cert file was darker, having more regions masked out. I haven't tested it on a video yet, as clearly the current version works as-is. I'm more interested to know the reasons behind the discrepancy, or if you do something like set MOTION_BOUNDARIE_VALUE to 0 during train time and 255 for test time—or if I'm perhaps misunderstanding how the certs are calculated.

Thanks!
