customized input data

[holyseven]

🚀 Feature

Input data processing needs to be flexible and can be customized.

Motivation and Additional context

Currently, images are normalized according to natural images, like ImageNet statistics. However, for medical, remote sensing, and other types of 2D inputs (or even more complex data), current pipelines cannot deal with.

Alternatives

Maybe paddle.vision.transforms or other transformations can be used.
