VIDEO COLOUR COMPONENT PREDICTION METHOD AND APPARATUS, AND COMPUTER STORAGE MEDIUM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18353210 titled 'VIDEO COLOUR COMPONENT PREDICTION METHOD AND APPARATUS, AND COMPUTER STORAGE MEDIUM

Simplified Explanation

This patent application describes a method and apparatus for predicting video color components. It also includes a computer storage medium for storing the necessary data.

  • The method involves obtaining a first color component neighboring reference value and a first color component reconstructed value for a current coding block.
  • The first color component neighboring reference value represents a parameter for a neighboring reference sample of the coding block.
  • The first color component reconstructed value represents one or more reconstruction parameters for the color component of the coding block.
  • A weight coefficient is determined for the neighboring reference sample.
  • A scale factor is determined based on the weight coefficient and the first color component neighboring reference value.
  • A second color component predicted value is obtained for the current coding block using a linear model based on the scale factor.

Overall, this patent application presents a method and apparatus for predicting video color components using neighboring reference values and reconstruction parameters, ultimately improving the accuracy of color prediction in video coding.


Original Abstract Submitted

A video colour component prediction method and apparatus, and a computer storage medium are provided. The prediction method includes: obtaining a first colour component neighboring reference value and a first colour component reconstructed value corresponding to a current coding block, wherein the first colour component neighboring reference value represents a first colour component parameter corresponding to a neighboring reference sample of the current coding block, and the first colour component reconstructed value represents one or more reconstruction parameters of a first colour component corresponding to the current coding block; determining a weight coefficient corresponding to the neighboring reference sample; determining a scale factor according to the weight coefficient and the first colour component neighboring reference value; and obtaining a second colour component predicted value corresponding to the current coded block based on a linear model corresponding to the scale factor.
