Optical flow dataset normalization

Hello EVeryone,

When using optical folow data to train an autoencoder,should we normalize the optical flow data? If so, can we use the imagenet normalization parameters(mean=[0.485, 0.456, 0.406], std=[0.229, 0.224, 0.225])? Or, do we have to calculate the normalization parameters of the optical flow dataset?

Thank you
