I see that there are many example on object detection for Nvidia platform, so I don’t know where to start. I would to use my Jetson Nano to detect and track only person from a webcam. Could you suggest me a models? I see that with ssd-mobilenet-v2 I can get good fps. There is a way to select just person using detectnet in Jetson-inference or I need to re-train ssd-mobilenet-v1 only for person?
