Flexible Motion-Adaptive Video Coding with Redundant Expansions
Pascal Frossard, Pierre Vandergheynst, Adel Rahmoune
This paper presents a highly flexible video coding scheme (MP3D), based on the use of a redundant 3-D spatio-temporal dictionary of functions. Directionality and anisotropic scaling are key ingredients to the spatial components, that form a rich collection ...
2006Adaptive video delivery using semantics
The diffusion of network appliances such as cellular phones, personal digital assistants and hand-held computers has created the need to personalize the way media content is delivered to the end user. Moreover, recent devices, such as digital radio receive ...
EPFL2005Packetized Media Streaming with Comprehensive Exploitation of Feedback Information
Pascal Frossard, Christophe De Vleeschouwer
This paper addresses the problem of streaming packetized media over a lossy packet network, with sender-driven (re)transmission using acknowledgement feedback. The different transmission scenarios associated to a group of interdependent media data units ar ...
2005Intra-Adaptive Motion-Compensated Lifted Wavelets for Video Coding
Pierre Vandergheynst, Oscar Divorra Escoda
This paper investigates intra-adaptive wavelets for video coding with frame-adaptive motion-compensated lifted wavelet transforms. With motion-compensated lifted wavelets, the temporal wavelet decomposition operates along motion trajectories. However, vali ...
