Is this just needing more training of a frigate+ model at night? It seems to really struggle with parked cars in low light.
#Jittery frigate detection at night

probably more training, mine doesn't have these issues in less lit conditions
the problem is the box jumps from being slightly too high to way too low and that causes norfair to think it is moving so the region gets bigger, rinse and repeat. Once the object is considered stationary it should be a lot better but the problem really is that the box is not consistent for the car even with the same region

I feel like I’ve already submitted a ton from this camera tho

might be a lighting issue, especially with the shadow below the car
gritty sage
Yeah the car really fades into the shadow being a dark blue
main garnet
this is mine, detection is quite steady but it took a lot of training at night specifically to get there
gritty sage
Hmm yeah I just need to draw a few thousand more boxes lol
The motion box setting was on and you can see it wasn't actually registering any true motion
You would think there could be a way to stabilize the box when no motion is happening
Basically "this region isn't moving so keep the detection box at the size of the highest score" or something
main garnet
the detector is the source of truth
if we start ignoring the detector then a different scenario starts acting up when it worked before
in this case even with the same region the bounding box is different, so it comes down to a detection problem
gritty sage
It's getting multiple, different hits yeah
main garnet
I had similar issues where the hood would get detected as a separate car but training fixed that for me at least
if there are multiple boxes from a single detection, NMS based on the scores and overlap is already run
gritty sage
In a way the detector is making false motion, moving detections around when no video motion is actually occuring
One other question, in the explore tab, why does the cameras drop down have all the toggles enabled, but the all zones one doesn't when "all" is enabled at the top?

It works that way because sometimes a tracked object is in lighting conditions that don't register as motion. If we assumed everything was the same if no motion boxes existed, then we would end up with tracked objects stuck in their last location with motion. We tried this and it didn't go well.
gritty sage
Ha yeah it’s not an easy sounding problem for sure when the detector itself isn’t totally sure
main garnet

because it is more common to want to select a "middle amount" of cameras. So the camera dropdown makes it possible to start from no cameras selected or start from all cameras selected
gritty sage
Ahh it’s always two clicks to view just one camera but one for a zone
main garnet
yeah, that is the compromise to make it way less clicks to view all but a couple cameras
gritty sage
Can’t you pick a group too tho?
main garnet
that's a good point, can see what @peak thunder thinks
gritty sage
The pedantic part of me was mostly like “why do these two menus behave differently”
