I was wondering if the Frechet inception distance for two colored datasets would be the same than the FID calculated for the same datasets converted to grayscale.
I know that it depends on the feature extraction, which is the Inception network. And that is the question, I don't fully understand the role of color in CNNs. I thought that all color information is lost in the feature extraction, and in this case I grayscale and colored datasets would produce the same FID. But I am not sure about that.
