Perceptually-Driven Video Coding with the Daala Video Codec
Yushin Cho, Thomas J. Daede, Nathan E. Egge +5
The Daala project is a royalty-free video codec that attempts to compete with the best patent-encumbered codecs. Part of our strategy is to replace core tools of traditional video…
Daala: Building A Next-Generation Video Codec From Unconventional Technology
Jean-Marc Valin, Timothy B. Terriberry, Nathan E. Egge +4
Daala is a new royalty-free video codec that attempts to compete with state-of-the-art royalty-bearing codecs. To do so, it must achieve good compression while avoiding all of thei…
Daala: A Perceptually-Driven Still Picture Codec
Jean-Marc Valin, Nathan E. Egge, Thomas Daede +2
Daala is a new royalty-free video codec based on perceptually-driven coding techniques. We explore using its keyframe format for still picture coding and show how it has improved o…
Robust 3D Localization and Tracking of Sound Sources Using Beamforming and Particle Filtering
Jean-Marc Valin, François Michaud, Jean Rouat
In this paper we present a new robust sound source localization and tracking method using an array of eight microphones (US patent pending) . The method uses a steered beamformer b…
Predicting Chroma from Luma with Frequency Domain Intra Prediction
Nathan E. Egge, Jean-Marc Valin
This paper describes a technique for performing intra prediction of the chroma planes based on the reconstructed luma plane in the frequency domain. This prediction exploits the fa…
Channel Decorrelation For Stereo Acoustic Echo Cancellation In High-Quality Audio Communication
Jean-Marc Valin
In this paper, we address an important problem in high-quality audio communication systems. Acoustic echo cancellation with stereo signals is generally an under-determined problem…
