For SCIs with natural regions, the proposed method achieves a bit-rate reduction of up to 11. 6% and 1. 52% with respect to HEVC and the previous version of the SCF.

For each pixel to be encoded, a probability distribution is estimated based on the neighboring pattern and the occurrence of that pattern in the already encoded image.
