[Demo]
照片对象识别
$./detectnet-console.py --network=ssd-mobilenet-v2 input.jpg output.jpg

Camera 对象识别
$./detectnet-camera.py                             # using SSD-Mobilenet-v2, default MIPI CSI camera (1280x720)
$./detectnet-camera.py --network=ssd-inception-v2  # using SSD-Inception-v2, default MIPI CSI camera (1280x720)
$./detectnet-camera.py --camera=/dev/video0        # using SSD-Mobilenet-v2, V4L2 camera /dev/video0 (1280x720)
$./detectnet-camera.py --width=640 --height=480    # using SSD-Mobilenet-v2, default MIPI CSI camera (640x480)
