The goal of this bachelor thesis is to extend the work of Lugmayr et al. [1] in order to improve the generative network by using a learned image down sampler motivated from CAR network [2] instead of bicubic down sampling. The aim is to achieve a better image quality or a more robust SR network for images of Real-World data distribution.
