Latest Patents

Van Luong Pham holds a patent for "Techniques for contouring/banding artifact removal in compressed image/video." This patent presents low complexity, hardware-friendly techniques designed for video coding systems. The methods aim to mitigate banding artifacts while maintaining compression efficiency. The proposed techniques consist of two stages: a banding detection stage and a de-banding stage. The detection stage identifies regions where banding artifacts may be present based on gradient information. The de-banding stage applies corrective techniques to these identified regions. When implemented over the AV1 video coding standard, the technique significantly improves subjective quality at a reasonable hardware implementation cost.
