Claim 10:
11. One or more computer-readable non-transitory storage media embodying software that is operable when executed to:
receive an intra-prediction type for a video frame;
in response to the intra-prediction type being a first type, receive as neighboring samples: a reconstructed left neighboring chroma sample, a reconstructed top neighboring chroma sample, a reconstructed left neighboring luma sample and a reconstructed top neighboring luma sample;
in response to the intra-prediction type being a second type, receive as the neighboring samples: a predicted left neighboring luma sample, a predicted left neighboring chroma sample, the reconstructed top neighboring luma sample, and the reconstructed top neighboring chroma sample;
in response to the intra-prediction type being a third type, receive as the neighboring samples: the reconstructed top neighboring chroma sample and the reconstructed top neighboring luma sample;
filter the neighboring samples to form filtered samples;
down sample the filtered samples;
determine a first parameter and a second parameter of a model using the filtered samples; and
predict chroma block samples based on the first parameter, the second parameter, and the filtered samples.
