Keynote Talks

Optimizing light field camera designs (Mon 16:00)

Computational photography is pushing sophisticated computational thinking deeper into the imaging pipeline. For example, light field cameras record higher-dimensional data than conventional cameras, and enable new functionality, like depth inference, refocusing and correcting lens aberrations in post-processing. This talk will review the theory and intuition of light field camera design, and describe the resulting transformation of design considerations and opportunities in core subsystems: optics, sensors and processors. The development of such cameras opens the door to the use of light field cameras for computer vision and machine learning.

Digital Avatars for All: Interactive Face and Hair (Tue 16:00)

Although realistic face/hair modeling and animation technologies have been widely employed in computer generated movies, it remains challenging to deploy them in consumer-level applications such as computer games, social networks and other interactive applications. The main difficulties come from the requirement of special equipment, sensitivity to daily environments, laborious manual work and high computational costs. In this talk, I will introduce our recent research on realistic face/hair modeling and animation, aiming at interactive applications and ordinary users. In particular, I will describe fully automatic approaches to real-time facial tracking and animation with a single web camera, methods for modeling hairs from images, and real-time algorithms for realistic hair simulation.
