Hi,
Can you share one of the images in your dataset and also the method to visualize transformed images?
It would be great also if you could combine your questions into single topic as they are highly correlated.

  
    
    
    Normalisation necessary for image reconstruction? vision
  
  
    I have a dataset which needs to be denoised. When I was looking at the images of my dataloader which are fed into network I saw that the images from dataloader and images in my dataset are very different. Now the only transformation I used are resize and ToTensor(). 
Is it because of ToTensor()? Is it normalizing my image and is that causing my model to learn nothing? 
Can I stop this?
