Hi there! I am searching for a self hosted solution to recognise
objects in photos. I have an incoming flow of jpeg images from a
surveillance camera. They are made by motion trigger in camera, but
about 70% of them are rubbish because they are triggered by movement
of tree branches or grass. I need a solution to filter this flow and
use in the next step (send to the telegram channel) only pictures that
contain people or cars. Please, tell me if you know any suitable
solutions!

I think tensorflow can do that

[Codeproject AI
server](https://www.codeproject.com/Articles/5322557/CodeProject-AI-
Server-AI-the-easy-way) sounds suitable for your use case. It provides
an API for object recognition with various backends (different models,
CUDA, Coral acceleration, etc), supports multiple platforms and very
easy to deploy.

Good solution but not for my current case because i haven't computer
equipment on permanent basis in installation area (countryside), only
camera and nvr that saves video locally and send pictures to remote
ftp through poor LTE internet

Fair enough!
