Calculating our own image stats (imagenet_stats, cifar_stats etc.)

I’m interested in calculating my own image stats for normalization. I think this is worth trying because my images (medical) come from a different distribution than the CIFAR and ImageNet datasets. The values of these stats in fastai are: imagenet_stats: ([0.485, 0.456, 0.406], [0.229, 0.224, 0.225]) cifar_stats: ([0.491, 0.482, 0.447], [0.247, 0.243, 0.261]) mnist_stats : ([0.15, 0.15, 0.15], [0.15, 0.15, 0.15]) If I’m reading this correctly, these are the means and standard deviation…
