Need help on data normalization

I used nn.spatialcontrastivenormalization for data normalization on Torch.
However, I cannot find it on pytorch. Is there any similar? or plan on implementing?

or similar function of image.lcn on torch

We dont expose that class in PyTorch. But you can implement it using autograd functions like mean, std and division /.
No plans of implementing / porting it, but we will take pull requests.
