I’m currently using ResNet152 to extract features from a video, where the extracted features are of shape (1842, 2048). I would like to also extract features for the same video, but horizontally flipped. I see 2 ways to do so:

Flip the video horizontally, then re-compute features
Flip the ResNet152 features for each frame from the already-computed features on the original video

The 2nd option is attractive when considering computing resources - how would that be achieved? Are ResNet152 features able to be “flipped” like this? If so, I’m guessing it can be done with torch.flip?
Thank you for reading! Hoping someone can guide me in the right direction.
