Call for papers

Image restoration and image enhancement are key computer vision tasks, aiming at the restoration of degraded image content, the filling in of missing information, or the needed transformation and/or manipulation to achieve a desired target (with respect to perceptual quality, contents, or performance of apps working on such images). Recent years have witnessed an increased interest from the vision and graphics communities in these fundamental topics of research. Not only has there been a constantly growing flow of related papers, but also substantial progress has been achieved.

Each step forward eases the use of images by people or computers for the fulfillment of further tasks, as image restoration or enhancement serves as an important frontend. Not surprisingly then, there is an ever growing range of applications in fields such as surveillance, the automotive industry, electronics, remote sensing, or medical image analysis etc. The emergence and ubiquitous use of mobile and wearable devices offer another fertile ground for additional applications and faster methods.

This workshop aims to provide an overview of the new trends and advances in those areas. Moreover, it will offer an opportunity for academic and industrial attendees to interact and explore collaborations.

This workshop builds upon the success of the previous NTIRE editions: at CVPR 2017 and 2018 and at ACCV 2016 . Moreover, it relies on all the people associated with the NTIRE past events such as organizers, PC members, distinguished speakers, authors of published paper, challenge participants and winning teams.

Title:Blind Deconvolution: A Journey from Model-Based to Deep Learning Methods

Abstract: Blind deconvolution has enjoyed quite a remarkable progress in the last few decades thanks to developments in optimization and machine learning. To a large extent today several algorithms allow to recover a sharp image from a blurry one without additional knowledge about the blur. This is a remarkable achievement given the extreme ill-posedness of this mathematical problem. Very interesting steps forward have been made in the last decade, when fundamental inconsistencies in the formulation, such as priors favoring the blurry solution, were exposed. This has led to the study of novel formulations that favor sharp over blurry images and result in state of the art performance with robustness to noise in real images. More recently, developments in deep learning have led to a fundamentally different approach to this problem, where enough data can adequately represent a realistic blur model and allow a neural network to learn how to remove blur from images. Approaches in deep learning have led to surprising results, where rather complex blur artifacts are removed effectively and efficiently. We give an account of the latest developments and show their strengths and weaknesses.

Title: A Style-Based Generator Architecture for Generative Adversarial Networks

Abstract: We propose an alternative generator architecture for generative adversarial networks, borrowing from style transfer literature. The new architecture leads to an automatically learned, unsupervised separation of high-level attributes (e.g., pose and identity when trained on human faces) and stochastic variation in the generated images (e.g., freckles, hair), and it enables intuitive, scale-specific control of the synthesis. The new generator improves the state-of-the-art in terms of traditional distribution quality metrics, leads to demonstrably better interpolation properties, and also better disentangles the latent factors of variation. To quantify interpolation quality and disentanglement, we propose two new, automated methods that are applicable to any generator architecture. Finally, we introduce a new, highly varied and high-quality dataset of human faces.

Bio: Tero Karras is a principal research scientist at NVIDIA Research, which he joined in 2009. His current research interests revolve around deep learning, generative models, and digital content creation. He has also had a pivotal role on NVIDIA's real-time ray tracing efforts, especially related to efficient acceleration structure construction and dedicated hardware units.

Title: Visualizing and Understanding GANs

Abstract: Generative Adversarial Networks (GANs) have recently achieved impressive results for many real-world applications. However, they have not been well visualized or understood. How does a GAN represent our visual world internally? What causes the artifacts in GAN results? How do architectural choices affect GAN learning? Answering such questions could enable us to develop new insights and better models. In this talk, we present GAN Dissection, an analytic framework to visualize and understand GANs at the unit-, object-, and scene-level. We first identify a group of interpretable units that are closely related to object concepts using a segmentation-based network dissection method. Then, we quantify the causal effect of interpretable units by measuring the ability of interventions to control objects in the output. We show several practical applications of our framework, from comparing internal representations across different layers, models, and datasets, to improving GANs by locating artifact-causing units, to interactively manipulating objects in both generated images as well as natural photos.

Bio: Jun-Yan Zhu is a postdoctoral researcher at MIT CSAIL. He obtained his Ph.D. in computer science from UC Berkeley after studying at CMU and UC Berkeley, and before that, received his B.E. from Tsinghua University.

Sylvain Paris

Title: Photography Made Easy

Abstract: With digital cameras and smartphones, taking a picture has become effortless and easy. Autofocus and autoexposure ensure that all photos are sharp and properly exposed. However, this is not sufficient to get great photos. Most pictures need to be retouched to become aesthetically pleasing. This step still requires a great deal of expertise and a lot of time when done with existing tools. Over the years, I have dedicated a large part of my research to improving this situation. In this talk, I will present a few recent results where we use existing photos by artists as models to make ordinary pictures look better.

Bio: Sylvain Paris is a researcher at Adobe Research in Cambridge Massachusetts. Before that, he was a post-doc at MIT with Frédo Durand and a student at INRIA in Grenoble with François Sillion. His interests cover computational photography and image processing. He has done several contributions to the field of photo and video editing, the goal being to help novices and experts create better pictures and videos. Some of the technology that he has invented is now available in commercial software such as Photoshop and Lightroom.

Title: Learning Network Path Selection for Image Restoration

Abstract: Very deep Convolutional Neural Networks (CNNs) have greatly improved the performance on various image restoration tasks. However, this comes at a price of increasing computational burden, which limits their practical usages. We believe that some corrupted image regions are inherently easier to restore than others since the distortion and content vary within an image. To this end, we propose Path-Restore, a multi-path CNN with a pathfinder that could dynamically select an appropriate route for each image region. We train the pathfinder using reinforcement learning with a difficulty-regulated reward, which is related to the performance, complexity and the difficulty of restoring a region. We conduct experiments on denoising and mixed restoration tasks. The results show that our method could achieve comparable or superior performance to existing approaches with less computational cost. In particular, our method is effective for real-world denoising, where the noise distribution varies across different regions of a single image.

Bio: Chen Change Loy is a Nanyang Associate Professor with the School of Computer Science and Engineering, Nanyang Technological University, Singapore. He is also an Adjunct Associate Professor at the Chinese University of Hong Kong. He received his PhD (2010) in Computer Science from the Queen Mary University of London. Prior to joining NTU, he served as a Research Assistant Professor at the MMLab of the Chinese University of Hong Kong, from 2013 to 2018. He is the recipient of 2019 Nanyang Associate Professorship (Early Career Award) from Nanyang Technological University. His research interests include computer vision and deep learning, with a focus on face analysis, image processing, and visual surveillance. He has published more than 100 papers in top journals and conferences of computer vision and machine learning. He and his team proposed a number of important methods for image super-resolution including SRCNN, SFTGAN and ESRGAN. As a co-author, his journal paper on SRCNN was selected as the `Most Popular Article' by IEEE Transactions on Pattern Analysis and Machine Intelligence in 2016. It remains as one of the top 10 articles to date. ESRGAN has been widely used to remaster various classic games such as Half-Life, Resident Evil 2, Morrowind, and Final Fantasy 7. He serves as an Associate Editor of the International Journal of Computer Vision (IJCV) and IET Computer Vision Journal. He also serves/served as the Area Chair of CVPR 2019, BMVC 2019, ECCV 2018, and BMVC 2018. He is a senior member of IEEE.

Title: Computation and Photography: How the Mobile Phone Became a Camera

Abstract: The first camera phone was sold in 2000, when taking pictures with your phone was an oddity, and sharing pictures online was unheard-of. Today, barely twenty years later, the smartphone is more camera than phone. How did this happen? This transformation was enabled by advances in computational photography -- the science and engineering of making great images from small form factor, mobile cameras. Modern algorithmic and computing advances have changed the rules of photography, bringing to it new modes of capture, post-processing, storage, and sharing. In this talk, I'll describe some of the history and more recent elements of this technology, including a multi-frame super-resolution and denoising algorithm developed by my team at Google, and launched in Pixel phones.

Bio: Peyman leads the Computational Imaging team in Google Research, part of Google AI Perception. Prior to this, he was a Professor of Electrical Engineering at UC Santa Cruz from 1999-2014. He was Associate Dean for Research at the School of Engineering from 2010-12. From 2012-2014 he was on leave at Google-x, where he helped develop the imaging pipeline for Google Glass. Most recently, Peyman's team at Google developed the digital zoom pipeline for the Pixel phones, which includes the multi-frame super-resolution ("Super Res Zoom") pipeline, and the RAISR upscaling algorithm. In addition, the Night Sight mode on Pixel 3 uses our Super Res Zoom technology to merge images (whether you zoom or not) for vivid shots in low light. Peyman received his undergraduate education in electrical engineering and mathematics from the University of California, Berkeley, and the MS and PhD degrees in electrical engineering from the Massachusetts Institute of Technology. He holds 15 patents, several of which are commercially licensed. He founded MotionDSP, which was acquired by Cubic Inc. (NYSE:CUB). Peyman has been keynote speaker at numerous technical conferences including Picture Coding Symposium (PCS), SIAM Imaging Sciences, SPIE, and the International Conference on Multimedia (ICME). Along with his students, he has won several best paper awards from the IEEE Signal Processing Society. He is a Distinguished Lecturer of the IEEE Signal Processing Society, and a Fellow of the IEEE "for contributions to inverse problems and super-resolution in imaging."
