Why Volumetric Scattering?
Computer vision and graphics are multi-disciplinary fields of research with a wide spectrum of applications that impact our daily lives. Today, cameras and displays are ubiquitous and the amount of imagery generated is overwhelming. That said, most of the computer generated imagery in video games, movies and scientific simulations are of scenes on clear days or nights. Volumetric scattering effects such as the beautiful fog rolling down the hills, the bluish haze of mountains, the eerie night mist, the brilliance of underwater effects, or the light streaming through clouds provide pure artistic and entertainment value. Such effects are used in movies and paintings to portray different moods, and are captured in photographs to provide realism. Besides digital entertainment, scattering effects are also simulated for training human operators in safety, medical and hazardous situations --- pilots landing through fog, soldiers conducting reconnaissance in dusty desert terrain, divers exploring ocean depths, and doctors looking for cancerous tissue. In the absence of scattering effects, current renderings appear unnatural and cartoonish.
Analogously, most computer vision systems have not enjoyed success when
deployed in uncontrolled outdoor environments. Today, modern vehicles have
(semi-)automatic intelligent transportation systems that assist drivers in
navigation. However, they fail to work in common bad weather conditions
such as fog, snow and rain, indeed when they are most required. Similarly,
field robots fail to navigate in hazardous environments such as smoke and
dust, underwater exploration tasks are hindered by murky water, aerial and
satellite imaging tasks are made difficult due to the presence of the
atmosphere, and finally, medical image analysis is made hard due to the
complex scattering properties of tissues. Unfortunately, however, most
vision techniques are designed to perform only in clear air. Even
with perfect clear-air performance, scattering effects are the one
fundamental hurdle that can stop vision from having successful impact in
This one-day symposium presents a series of invited talks from researchers in various fields including vision, graphics, underwater imaging, oceanography, medicine, astrophysics and nature photography.
