Bloody Spiders!!!!
Regarding false positives when using CPAI 2.0.8 with Object Detection (YOLOv5 .NET), I have a 85% min confidence filter for "person" and still the bloody spiders are triggering alerts.
is it worth using a custom model to get less false positives? or somehow adjusting the image scale of whats considered a person?
Like when the spiders right on the lens taking up 70% of the screen and its still getting triggered as a person, that an obvious flag to tell it cant be a person.
it works the other way to, bloody birds!!! their far to tiny to be a person, yet still getting triggered.
Any thoughts on what to do here?
What I do is maintain low expectations for the “intelligence” portion of AI. I have a camera where I found rabbits were most often detected as birds, so I alert on rabbits and birds. I want to be alerted if deer are present, and during one rainstorm I kept getting “deer” alerts because of a clump of weeds that resembled a running deer. Last week, during a thunderstorm, I was alerted to a “dog” in the backyard that was actually a hose cart. And, just today, setting up the delivery custom model to alert me when the mail truck comes up the road, a Snap-On tool truck was identified as a FedEx truck with 90% confidence!
In my experience , the AI greatly reduces false alerts from spider webs, shadows, and wind-blown trees, but it’s not yet good enough that I’d trust it enough to allow it to disturb my sleep.
