Does anyone know how NaN values are treated when extracting the features? Do you think it may influence the results?

Vlados09 commented 4 years ago

Well, they are currently fully ignored... I was thinking about what we could do for video is do some interpolation somehow if there is a face missing in a frame. Are you getting a lot of NaN's?

Tymon555 commented 4 years ago

I haven't measured what is the proportion of NaNs. Might be worth trying

Vlados09 commented 4 years ago

I've been looking through it and it seemed like there were almost no NaN's. They would've been eliminated during FDHH or if not there would be an error raised
