Abstract: In Versatile Video Coding (VVC), Cross-component Linear Model. (CCLM) predicts chroma samples by assuming a linear relationship between luma.

We propose improving the prediction performance by applying horizontal filtering to luma samples which removes the horizontal aliasing effect. Experimental ...
