A low-complexity multiple description video coder based on 3D-transforms
TL;DR: The paper presents a multiple description (MD) video coder based on three-dimensional (3D) transforms that has low computational complexity and high robustness to transmission errors and is targeted to mobile devices.
Proceedings ArticleDOI

TL;DR: A local adaptive filter based on discrete cosine transform in overlapping blocks is proposed and a threshold is set locally based on a noise standard deviation estimate obtained for each block.

Proceedings Article
Radar frequency band invariant pedestrian classification
TL;DR: Two new approaches are proposed for pedestrian classification based on the observations based on higher order spectral invariants estimated from the Doppler spectrum based on new features called local binary mask and robustness to operating frequency of the radar.
Proceedings ArticleDOI
Opengl-Based Control of Semi-Active 3D Display
TL;DR: This work investigates if the precise delivery of different images to each eye of the observer can be handled by the fixed optics of a multiview 3D display, and if continuous head parallax can be achieved.
