Predicting Chroma from Luma in AV1
Luc N. Trudeau, Nathan E. Egge, David Barr
Chroma from luma (CfL) prediction is a new and promising chroma-only intra predictor that models chroma pixels as a linear function of the coincident reconstructed luma pixels. In…
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…
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…
Daala: A Perceptually-Driven Next Generation Video Codec
Thomas J. Daede, Nathan E. Egge, Jean-Marc Valin +2
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…
