CamPose.inf in the DFA Dataset

[bennyguo]

Hi, thanks for releasing the code and data for this amazing work!

I believe that the CamPose.inf files in the DFA Dataset contain camera-to-world transformation matrices, but in the README (also in the code) you refer to them as extrinsics, which conventionally describe world-to-camera transformations. I think it would be better to rephrase to avoid potential misunderstandings.
