Latest Patents

One of Yee Jin Lee's latest patents is titled "Segment-based reshaping for coding high dynamic range video." This patent describes techniques for generating and compressing composer metadata that allows a decoder to produce a corresponding output in high dynamic range from a standard-dynamic range (SDR) video input. The proposed methods include a static, sequence-based architecture, a two-stage, scene-based, distributed solution with centralized post-processing, and a single-stage distributed solution using overlapped segments. Additionally, techniques to minimize the amount of transmitted composer metadata are also outlined.

Another significant patent is "Encoding and decoding reversible production-quality single-layer video signals." This invention involves generating a tone-mapping function that maps high dynamic range input images into reference tone-mapped images of a narrower dynamic range. It includes the derivation of a luma forward reshaping function and a chroma forward reshaping mapping, which are essential for predicting codewords of the forward reshaped images. The patent also discusses the transmission of backward reshaping metadata to recipient devices, enabling them to generate necessary reshaping functions.
