How to ignore stationary false positives?

[raintonr]

I have previously asked about ignoring false positive that seem to suddenly appear in part of the frame and do not move (see #10414). The answer at the time was that logic was already improved in 0.14. I have now been running 0.14.1-f4f3cfa for some time and still see this problem.

False positives occur more often at night and/or in bad weather (when there can be rain or snow on the lens). While I get that false positives can occur, what I do not understand is that when they appear in frame and don't move, why are they causing detections, when I was told in the issue above that an object had to move to be considered a valid detection?

Here's a couple of examples:

If Frigate does not flag objects as detections unless they move, it would be super useful to see the path that the object followed up to the point it was thought a valid target in order to investigate this further?

If the behaviour I am seeing is as designed, any suggestions as to how to avoid detections like this?

BTW, I did think about increasing height and/or area necessary, but that would not work as sometimes the false positive is much larger:

you can increase the min_score and threshold, that may help with falses.

In 0.15 you'll be able to see the different moments an object was detected during its lifecycle to debug that
