A Super Resolution Generative Adversarial Network (SRGAN) with the purpose of upscaling image resolutions by a factor of two using deep learning. This way, a picture which initially appears pixellated and/or blurry can be modified so that the features are quite more distinguishable.

Esed TensorFlow 2.0 as the API for creating and training the SRGAN. The model was built with Keras and trained on the MS COCO Dataset. Numpy, Matplotlib, and several other libraries were used for image preprocessing.

Winner of the #PoweredByTF 2.0 Challenge.
