Claim 0:
1. A method comprising:
receiving, by a decoder, an intra-prediction type for a video frame;
in response to the intra-prediction type being a first type, 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 are received by the decoder as neighboring samples;
in response to the intra-prediction type being a second type, 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 are received by the decoder as the neighboring samples;
in response to the intra-prediction type being a third type, the reconstructed top neighboring chroma sample and the reconstructed top neighboring luma sample are received by the decoder as the neighboring samples;
filtering, by the decoder, the neighboring samples to form filtered samples;
down sampling, by the decoder, the filtered samples;
determining, by the decoder, a first parameter and a second parameter of a model using the filtered samples; and
determining, by the decoder, predicted chroma block samples based on the first parameter, the second parameter, and the filtered samples.
