Title: Toward Real-World Image Super-Resolution: Challenges and Approaches
Abstract: Image Super Resolution (SR) which aims to reconstruct a high-resolution (HR) image from a low-resolution (LR) input, plays an essential role in computer vision, digital photography, and many real applications. Recently, a plethora of SR methods have been developed based on deep CNNs and large-scale datasets. However, most of the state-of-the-art methods still do not generalize well to real-world scenarios even though they perform relatively well on public benchmarks. In this talk, we will address some of the technical issues and challenges in the real-world SR problem including the domain gap, arbitrary scale transformation, and real-time processing issues. And then we introduce new approaches to tackle these challenges by learning unknown real down-sampling process via GAN with new effective losses, allowing generalized Image SR under arbitrary transformation, and optimizing the network structures via adaptive quantization and pruning. We empirically demonstrate that our new strategie
