Computational imaging: Seeing the invisibleSpeaker: Diego Gutierrez – Zaragoza, Spain
Topic(s): Graphics and Computer-Aided Design
AbstractThe field of computational imaging combines optics and computation to overcome the physical limitations of current cameras, to be able to capture visual information of the world that would be impossible to capture otherwise. In this talk, I will discuss the general principles of computational imaging, and present two examples. The first shows computation in the spatial domain, creating coded apertures that allow us to recovered information lost due to depth-of-field blur. In the second example I will present femtophotography, a technique that allows us to obtain an effective frame rate of one billion frames per second: this is fast enough to watch light in motion as it interacts with objects in a scene, and allows to analyze the richness of these interactions with the slowest-motion camera ever built. This technique is now being developed further both in the context of a DARPA project, and in collaboration with NASA to explore lunar caves without the need to send an astronaut or a robot.
