Why isn't Deepstack correctly identifying cars?

[wittaj]

As I have said many times, DeepStack, and especially night time in B/W, struggles with trying to detect images on the edges of the field of view.

You can try running it in color or if B/W then play with brightness and contrast so that there is more difference.

What does 'occupied' mean though?

Occupied means it sees an object that isn't moving. It is how parked cars are not identified when it sends images for analysis.

The really odd part of the previous .dat analysis is the it shows the BBQ (identified as chair) as an object in motion. Huh? But I'm not all that surprised, as I have seen similar oddities from DeepStack.
In daytime, the combined.pt works quite well, and with reasonable analysis times (even on CPU only, no NVIDIA card). The dark.pt is just a bit of a monster in terms of processing time for a CPU only setup, and with so-so results for B/W IR only scenes. I eagerly await news from @MikeLud1 on a new version of dark.pt, supposedly in the works. (Edit: he just updated his timeline for that this evening, it is looking like he hopes to release a new version by the end of this month).

Where does it say that? Doesn't 'occupied' mean that it's detected stationary objects?

Yes, the final "result" status shows as occupied, but the two colored dots next to some of the individual frame analyses/ identified objects are indicative of motion. Of course, sometimes all it takes for "motion" to be picked up by BI is a change in lighting, which is the likely explanation here.

Do you mean the two overlapping blue squares with yellow outlines?

Yes, exactly. I highly recommend a review of all the tips and tricks of Deepstack over on the official BlueIris forums, there are links within many of these pages to the webinars associated with topics.
