[sayannath]

Hello, @ameenaltajer Could you kindly review the PR? I have Added the Zero-DCE model to this repository.

The Zero-DCE model is a TensorFlow Lite model for low-light image enhancement. The model is proposed in [1]. Original model weights are used from [2].

Thanks for your contribution @sayannath!

A couple of suggestions - could up update your repo with the following please:

• Make it clear that your repo provides notebooks to convert the models to tflite.
• Rename src folder to notebooks
• Incorporate what you wrote above to your repo README so that the readers know what Zero-DCE is:
