This repository contains the code to compute the Fréchet Video Distance (FVD) as described in https://arxiv.org/abs/1812.01717.
FVD is implemented in tensorflow and requires tensorflow and tensorflow-hub to be available. An example is available here.
Given a tensor of real videos, and a tensor of generated videos that both have dimensionality [NUMBER_OF_VIDEOS, VIDEO_LENGTH, FRAME_WIDTH, FRAME_HEIGHT, 3] with values in 0-255, FVD is computed as
from frechet_video_distance import frechet_video_distance as fvd
result = fvd.calculate_fvd(
fvd.create_id3_embedding(fvd.preprocess(real_videos, (224, 224))),
fvd.create_id3_embedding(fvd.preprocess(generated_videos, (224, 224))))If you are using FVD please cite us!
