Hi,
You can find below a super-resolution example:
1. For a frozen pb file from TensorFlow v1.x, please convert it via .pb->uff->TRT
flow.
Other, please convert the file into ONNX format first.
**2.**In general, the input size is identical to the network input size.
For example, YOLO uses 608 or 416 as input.
3. Yes. You can do it with other multimedia libraries, ex. OpenCV.
Below is an example of TensorRT+OpenCV for your reference.
Thanks.
