• It's pretty alpha and not very flexible, but works.
• Testing/Training in Colab possible, since training Code is available in Yukariin/DFNet. Thank you Yukariin.
• Attempt to add Differentiable Augmentation.
• TensorboardX
• Added loss functions.
• Added image metrics.

Deep image completion usually fails to harmonically blend the restored image into existing content, especially in the boundary area. Our method handles with this problem from a new perspective of creating a smooth transition and proposes a concise Deep Fusion Network (DFNet). Firstly, a fusion block is introduced to generate a flexible alpha composition map for combining known and unknown regions. The fusion block not only provides a smooth fusion between restored and existing content, but also provides an attention map to make network focus more on the unknown pixels. In this way, it builds a bridge for structural and texture information, so that information can be naturally propagated from known region into completion. Furthermore, fusion blocks are embedded into several decoder layers of the network. Accompanied by the adjustable loss constraints on each layer, more accurate structure information are achieved. The results show the superior performance of DFNet, especially in the aspects of harmonious texture transition, texture detail and semantic structural consistency. More detail can be found in our paper
