The application for the patent was published on June 05, 2026, under issue no. 23/2026.
Abstract: A method for using Extrapolation Intra Prediction (EIP) to code pixel blocks is provided. A video coder receives data to be encoded or decoded as a current block of pixels of a current picture of a video. The video coder inherits a previously used linear model for extrapolation intra prediction (EIP) that is derived based on samples in a template region neighboring a previously coded block, the template region occupying an area that extends beyond at least one of top and left edges of the previously coded block. The video coder applies the inherited linear model to generate a predictor of the current block by using reconstructed samples or predicted samples of the current block as input to a filter to generate samples of the predictor. The video coder encodes or decodes the current block by using the predictor.
