Multi-Frame Analysis: The Future of Video Processing
Speakers:
Nikola Bozinovic
Abstract:

MotionDSP makes software that significantly improves video from a wide range of sources -- from mobile phones to surveillance cameras. Its patented, multi-frame video enhancement technology is available in Ikena, a video forensic solution, and in vReveal, a Windows application for consumers. High-fidelity motion estimation plays a critical role in almost any video processing technology. The open-loop nature of MotionDSP''s multi-frame video reconstruction framework requires a departure from quantized block-based motion estimation concept, commonly used in video encoding, as super-resolution temporal filtering can not rely on a prediction error to compensate for motion estimation inaccuracies. The need to use floating-point accurate motion fields, coupled with a multi-frame nature of the algorithm, makes GPGPU a natural choice when addressing this massive computational problem. This talk will provide an overview of MotionDSP''s video technology and products, as well as details of the design and performance challenges of MotionDSP''s multi-frame video pipeline, one of the first commercial video processing solutions fully ported to GPU architecture.
