Abstract:
A taxonomy of scattering phenomena and how to treat them efficiently, by leveraging the wealth of knowledge from computer graphics and computer vision. This course shows a wide range of multidisciplinary applications in both overlapping fields, from appearance modeling to vision in bad weather, and reviews measurement techniques.
Computer graphics and computer vision deal with acquiring, interpreting, and presenting the rich visual world around us. These are exciting multidisciplinary fields of research with a wide spectrum of applications that affect our daily lives. However, most current computer-generated imagery represents scenes with clear atmospheres, neglecting light scattering effects. Analogously, most computer-vision systems are not successful when deployed in uncontrolled outdoor environments.
This course addresses the challenges presented by light scattering in computer graphics and computer vision. Both fields have seen great advances over the past few years, but most of the existing algorithms still assume that light emitted by a source or reflected off a surface reaches the sensor unaltered. From a computer graphics perspective, this is due mainly to the complex interactions that occur and the high computational costs of simulating them. In computer vision, scattering has traditionally been considered as noise that one should ideally get rid of.
Scattering effects are one fundamental hurdle that must be overcome to significantly extend and enhance current state-of-the-art graphics and vision techniques and achieve successful impact in a wide range of domains. Given the increasing overlap between computer graphics and computer vision, including hot research fields such as computational photography, this course is useful for practitioners in both communities and everybody who studies the intersection of the two.

Prerequisites
None.
Intended Audience
This course is intended for people involved in computer graphics, computer vision, or related fields such as computational photography. It is particularly relevant to SIGGRAPH Asia attendees, as it provides a good understating of scattering phenomena, state-of-the-art techniques to simulate it and treat it, and a wide range of applications. It is especially useful for attendees who are interested in particular applications such as medical imaging, oceanography, driving simulators, and game production.
