Hey. I have a question. Have you used all the frames extracted from each video to identify a real/fake video? I tried looking for it but since I'm a starter I am facing difficulties in understanding the code. One more thing, you have used the scores obtained from each frame to classify the whole video right?

Hey @jessiZO ,

Sorry for the delay but we have been pretty busy in this period. For information regarding the experimental setup you can refer to the paper we have presented at ICPR2020. Answering your questions: we used 32 frames per video both in training and in testing, so to classify a whole video we consider the scores extracted from 32 frames selected equally spaced in time. Bests,

Edoardo

So you took average of the scores obtained from those 32 frames?

Yes, we took the average of the pre-sigmoid scores and then we computed the sigmoid on the mean score of the whole video :)

The split procedure that you followed for celeb df dataset, will it handle the imbalance in the dataset?
