Latest Patents

One of Che-Wei Kuo's latest patents is titled "Sign prediction for block-based video coding." This invention provides a video decoding apparatus and method for transform coefficient sign prediction on the decoder side. The method involves selecting a set of candidate transform coefficients from dequantized transform coefficients and applying a template-based hypothesis generation scheme to select a hypothesis from multiple candidate hypotheses. It also includes determining a combination of sign candidates associated with the selected hypothesis to predict signs for the candidate transform coefficients. The method further estimates original signs based on the predicted signs and updates the dequantized transform coefficients accordingly.

Another notable patent is "Motion compensation considering out-of-boundary conditions in video coding." This invention outlines methods and apparatuses for video coding, where a decoder derives reference pictures for a current coding block. The decoder generates predictor samples based on a motion vector and determines if these samples are out-of-boundary. If so, it replaces the out-of-boundary samples with alternative predictor samples and generates the final prediction sample by averaging the values of the predictor samples.
