An immersive video experience with real-time view synthesis leveraging the upcoming MPEG-I distribution format

The upcoming MPEG Immersive Video (MIV) standard will enable storage and distribution of immersive video content over existing and future networks, for playback with 6 full or partial degrees of freedom of view position and orientation. The demo showcases a VOD server streaming MIV encoded immersive video contents up to a decoding client where an HMD is connected. The user can perceive the parallax as he moves his head (translation, rotation) when seated. The core contribution of the demo is a real-time GPU implementation of the virtual view synthesis at decoder side. An enhanced quality of rendered views is attained through a weighting strategy of source views contributions which leverages standardized metadata conveying information on the pruning decisions at encoder side.

Despite many modern applications of Deep Neural Networks (DNNs), the large number of parameters in the hidden layers makes them unattractive for deployment on devices with storage capacity constraints. In this paper we propose a Data-Driven Low-rank (DDLR) method to reduce the number of parameters of pretrained DNNs and expedite...

Recently, learning methods have been designed to create Multiplane Images (MPIs) for view synthesis. While MPIs are extremely powerful and facilitate high quality renderings, a great amount of memory is required, making them impractical for many applications. In this paper, we propose a learning method that optimizes the available memory...
