Talk Title: Deep Learning Meets Computational Imaging: Combining Data-Driven Priors and Domain Knowledge

Talk Abstract: Neural networks have surpassed the performance of virtually any traditional computer vision algorithm thanks to their ability to learn priors directly from the data. The common encoder/decoder with skip connections architecture, for instance, has been successfully employed in a number of tasks, from optical flow estimation, to image deblurring, image denoising, and even higher level tasks, such as image-to-image translation. To improve the results further, one must leverage the constraints of the specific problem at hand, in particular when the domain is fairly well understood, such as the case of computational imaging. In this talk I will describe recent projects that build on this observation, ranging from reflection removal, to novel view synthesis, and video stitching.

Speaker's Biography: Orazio Gallo is a Senior Research Scientist at NVIDIA Research. He is interested in computational imaging, computer vision, deep learning and, in particular, in the intersection of the three. Alongside topics such as view synthesis and 3D vision, his recent interests also include integrating traditional computer vision and computational imaging knowledge into deep learning architectures. Previously, Orazio’s research focus revolved around tinkering with the way pictures are captured, processed, and consumed by the photographer or the viewer.

Orazio is an associate editor of the IEEE Transactions of Computational Imaging and was an associate editor of Signal Processing: Image Communication from 2015 to 2017. Since 2015 he is also a member of the IEEE Computational Imaging Technical Committee.

Talk Title: Fundamental Limits of Cell Phone Cameras

Talk Abstract: For the vast majority of people in the world, the best camera they have ever owned is in their current cell phone. Sales of phone camera modules approached $30 billion in 2018, almost three times the sales of all lasers, and will soon exceed four times the sales of all lasers. This is one of the most ubiquitous and successful optical devices ever. Fundamental laws of physics limit the performance of smartphone cameras, and these laws act against the marketing-driven aspiration for thinner and thinner camera modules. I shall show that the single most important optical parameter is the lens diameter D.

Speaker's Biography: Chris Dainty is consultant with FotoNation in Galway, Ireland, and holds Emeritus Professor appointments at universities in the UK and Ireland. Throughout his career, he has investigated problems in optical imaging, scattering and propagation. In these areas, he has co-authored or edited six books (including "Image Science" co-authored with Rodney Shaw in 1974), >180 peer-reviewed papers and >300 conference presentations. He has graduated 65 PhD students and mentored >75 post-docs. He is a recipient of the International Commission for Optics Prize, IoP’s Thomas Young Medal and Prize, OSA’s C.E.K. Mees Medal and OSA's Leadership Award. He is a fellow of The Optical Society, SPIE, The Institute of Physics, and the European Optical Society and a member of the Royal Irish Academy. He was President of The Optical Society (OSA) in 2011.
