Hi, I am using the MobileNetDetectionNetwork which uses a 300x300 input. I want to feed a square crop anywhere from the full 16x9 OAK frame into the NN. This square crop would be downsized to 300x300. Is there a simple way to do this onboard the OAK itself when configuring the OAK pipeline?

I want to pursue this path because MobileNetDetectionNetwork is unable to detect vehicles that are too small when the full frame is used as input to the NN. By getting a square crop of the ROI in the frame to feed to the NN, the NN would receive larger vehicles thus improving detection performance.

Thanks,
Gautam

    Hello gbanuru, you could use ImageManip node to crop a small square from the color frame.
    As for the configuration of the ImageManip, you could use something like this:

    manip.initialConfig.setCropRect(0.4, 0.4, 0.6, 0.6)
manip.initialConfig.setResize(300, 300)

    I hope this helps!
    Thanks, Erik
