Latest Patents

One of Shiyan Zhang's latest patents is titled "Fast parameter search for chroma from luma intra prediction in video coding." This invention provides a method for a video encoder to determine a value of a parameter of a linear CFL predictor for a coding block of a frame of a video. The process involves dividing a search range within a value range of the parameter into three portions by a starting value. The encoder determines cost values of parameter values from these portions and selects the value that corresponds to the lowest cost value. This innovation allows for more efficient encoding of video data.

Another notable patent is "Deriving in-loop filter parameters for video coding." This invention involves a video encoder performing inter prediction for a frame in a set of frames to generate prediction residuals. The encoder determines the value of a parameter of the in-loop filter by evaluating visual quality metrics for a set of training frames. The candidate parameter value that yields the highest visual quality metric is selected, enhancing the overall quality of the encoded video.
