Title:  Array cameras for interactive television

 

Abstract: Conventional broadcasting transmits to the viewer the exact image framed by a human camera operator. As array camera and computational imaging techniques advance, digital compositing of the broadcast signal from diverse data streams enables television to capture more action and increase viewer engagement. As internet protocol streaming replaces conventional broadcast numerous opportunities for interactive and social broadcasting arise. This talk reviews the history of array and multiscale cameras in the Duke Imaging and Spectroscopy Program and discusses recent studies of array cameras for gigapixel scale video and virtual reality broadcasting.

 

 

Bio: David Brady is the Michael J. Fitzpatrick Endowed Professor of Photonics at Duke University, where he leads the Duke Imaging and Spectroscopy Program. Brady's contributions to computational imaging systems include lensless white light tomography, optical projection tomography, compressive holography, reference structure tomography, coded aperture snapshot spectral imaging and coded aperture x-ray scatter imaging. He is the principal investigator for the DARPA AWARE Wide Field of View project, which aims to build compact streaming gigapixel scale imagers and the DARPA Knowledge Enhanced Exapixel Photography project, which focuses on code design for high pixel count spectral imagers. He is the author of Optical Imaging and Spectroscopy  (Wiley-OSA, 2009) and is a Fellow of IEEE, SPIE and OSA and was the 2013 winner of the SPIE Dennis Gabor Award.
