If there is only one camera, can I use crop or resize to generate virtual camera and use Cam-Convs?

Thank you for your work. It's been a great inspiration to me, and I have a puzzle.

There is only camera with same focal length in my dataset. Can cam-convs be used for training using virtual cameras generated by resize or crop?

I see that the results in the paper all used multiple cameras with different focal lengths, but in some case the camera parameters are fixed, and I'm not sure if using resize or crop to change camera intrinsic parameters will work.

I'm look forward to hearing from you!
