[FR] Multiple Redundant Detectors #14

Open mario-tux opened 4 years ago

mario-tux commented 4 years ago

I’m actually using Frigate (on Coral USB) + Deepstack (on CPU) + HA to get mobile notifications with snapshot&video of detected people on my cameras. I combine Frigate with Deepstack because TFlite models raise too many false positives. Coral is great to keep CPU load negligible but is very limited on detector capability/tuning: to use the CPU just to confirm the coral detections is fine to keep low CPU usage. The idea to combine (as a pipe) multiple detectors makes false positives disappear for me.

Would be possible to run multiple detectors on the same event/image to confirm its goodness?

The idea of passing a video stream through the sequence of detectors to refine a guess is valid, I thought of using Deepstack in my setup too.

The workflow inside the Watsor is not designed to to so at the moment however. Instead the workload from all cameras is balanced across all detectors to gain maximum performance, but not accuracy. Moreover, the models used in various detectors must be of the same type (SSD) as the output is generalised a bit.
