ENCODING METHOD, DECODING METHOD, AND DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18447885 titled 'ENCODING METHOD, DECODING METHOD, AND DEVICE

Simplified Explanation

The patent application describes an encoding method, decoding method, and device for video compression.

  • The encoding method determines the index of an intra prediction mode syntax element value set for a picture block.
  • A neural network is used to estimate the probability distribution of candidate intra prediction mode syntax element value sets based on input data representing the features of the picture block.
  • Entropy encoding is performed on the probability value related to the index of the intra prediction mode syntax element value set to obtain a bitstream.
  • This method improves video compression by efficiently encoding intra prediction mode syntax element value sets.


Original Abstract Submitted

This application discloses an encoding method, a decoding method, and a device. The encoding method includes: determining an index of an intra prediction mode syntax element value set of a current picture block; performing, by using a neural network, probability estimation on input data that represents a feature of the current picture block, to obtain probability distribution of a plurality of candidate intra prediction mode syntax element value sets, where the probability distribution represents respective probability values of the plurality of candidate intra prediction mode syntax element value sets; and performing entropy encoding on a probability value related to the index of the intra prediction mode syntax element value set of the current picture block based on the probability distribution of the plurality of candidate intra prediction mode syntax element value sets, to obtain a bitstream.
