Grayscale Images

[mnik17]

Hi @hassony2,

First of all thanks for the repo.

I wanted to use the pretrained kinetics RGB model to extract features from a dataset I created. Since my application should run in real time with limited computational resources I wanted to use grayscale images, since that way I only have to process one channel. My question was whether that would cause issue with the RGB model. If so, then I will convert my dataset to colour images.

Thank you
