Is OpenCV available for custom object detection?

Hi,
I am interested in deploying OpenCV on HL2 for custom object detection.
Is OpenCV available to do that?
If so, are there some reference tutorial videos?
(I notice that OpenCV can detect human faces, and I would like to detect other things, like construction vehicles.)
Thank you so much

Object detection with OpenCV often uses the DNN module these days, but unfortunately, OpenCV's DNN module is not compatible with the UWP platform and cannot be used with Hololens2.
Therefore, consider using a traditional Haar feature-based Cascade-type classifier or DNN inference with Unity's Barracuda.

OK, thank you for your information!
