报告题目(Title)：Learning Spatially Varying Pixel Exposures for Motion Deblurring

报告方式(Broadcast Link)：http://webinar.games-cn.org

报告摘要(Abstract)：

Computationally removing the motion blur introduced by camera shake or object motion in a captured image remains a challenging task in computational photography. Deblurring methods are often limited by the fixed global exposure time of the image capture process. The post-processing algorithm either must deblur a longer exposure that contains relatively little noise or denoise a short exposure that intentionally removes the opportunity for blur at the cost of increased noise.
We present a novel approach of leveraging spatially varying pixel exposures for motion deblurring using next-generation focal-plane sensor–processors along with an end-to-end design of these exposures and a machine learning–based motion-deblurring framework. We demonstrate in simulation and a physical prototype that learned spatially varying pixel exposures (L-SVPE) can successfully deblur scenes while recovering high frequency detail.

讲者简介(Speaker bio)：

Cindy M. Nguyen (https://ccnguyen.github.io/) is a PhD candidate in the Department of Electrical Engineering at Stanford University. Her research interests include denoising, deblurring, and depth estimation, among other challenges in computational photography. More recently, she has been interested in monocular depth estimation and tools to reconstruct 3D scenes. She received her bachelor’s and master’s degree from Stanford University.

报告题目(Title)：Efficient 3D Generative Models

报告方式(Broadcast Link)：http://webinar.games-cn.org

报告摘要(Abstract)：

In this talk, we’ll discuss 3D-aware generative models, a type of 3D GAN that trains from 2D images. We’ll gain an intuition of the problem of computational efficiency in neural rendering, and I’ll describe some recent techniques that have led to significant improvements in both quality and efficiency in 3D-aware generative models. These breakthroughs have led to new approaches that can generate photorealistic renderings in real-time, produce detailed geometry without requiring 3D ground-truth or multi-view training data, and enable a plethora of interesting applications, including photorealistic 3D avatar generation, and single-image 3D reconstruction.

讲者简介(Speaker bio)：

Eric Chan is a Ph.D. student at Stanford where he is advised by Gordon Wetzstein and Jiajun Wu. After studying mechanical engineering and computer science at Yale, he began learning the basics of computer vision in the hope of teaching robots and algorithms how to better understand the world around them. Over the last couple of years, his focus has shifted to the intersection of 3D graphics and vision—to generalization across 3D representations and 3D generative models.
