abstract = "Versatile Video Coding (VVC) procured an impressive coding gain with the help of various new coding tools. In the case of intra chroma coding, chroma separate tree (CST) and cross-component linear model (CCLM) show remarkable coding gain. However, there are only 8 prediction mode candidates in intra chroma coding which is much fewer than the 67 prediction mode candidates and up to 32 matrix-weighted intra prediction (MIP) mode candidates in intra luma coding. Excluding the three CCLM modes, the number of intra prediction mode candidates for chroma is just five, which is less than one tenth of luma channel which uses 67 intra prediction mode candidates except the MIP modes. In this paper, we investigate adding one more intra chroma prediction mode whose prediction direction is derived from the neighboring reconstructed area. The proposed method achieves a BDBR gain of 0.36\% and 0.26\% in the Cb and Cr channels without loss in Y channel under the all intra configuration.",
