How to improve image quality of torchvision.transforms.Resize

When I did such operation, the result image looks in poor quality.How to solve it?

You could specify the interpolation argument in transforms.Resize to another PIL.Image routine.

but I saw little change in all these setting. Do u have any recommendation of these interpolation?

I would assume you would see changes in the quality by trying out different algorithms.
Could you post an example result of such a bad quality image?
