IMAGE DECODING METHOD AND APPARATUS, AND IMAGE ENCODING METHOD AND APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18238340 titled 'IMAGE DECODING METHOD AND APPARATUS, AND IMAGE ENCODING METHOD AND APPARATUS
Simplified Explanation
The image decoding method involves:
- Identifying neighboring sub-blocks with the same motion vector adjacent to each other from a plurality of neighboring sub-blocks next to a current block.
- Determining a representative motion vector and representative location information for the identified neighboring sub-blocks.
- Determining a parameter of a model for calculating a motion vector based on the representative motion vector and representative location information.
- Determining the motion vector of a current sub-block within the current block based on the location information of the current sub-block and the parameter.
- Predicting the current block based on the motion vector of the current sub-block.
Potential applications of this technology:
- Video compression and encoding systems.
- Video streaming services.
- Virtual reality and augmented reality applications.
Problems solved by this technology:
- Efficient decoding of images with motion vectors.
- Improved image quality in video playback.
- Reduction of data transmission bandwidth in video streaming.
Benefits of this technology:
- Enhanced image decoding efficiency.
- Better video quality with reduced artifacts.
- Lower bandwidth requirements for video transmission.
Original Abstract Submitted
Provided are an image decoding method and apparatus. The image decoding method includes identifying at least two neighboring sub-blocks that have a same motion vector and are adjacent to each other from among a plurality of neighboring sub-blocks adjacent to a current block, determining a representative motion vector and representative location information corresponding to the at least two neighboring sub-blocks, determining a parameter of a model for determining a motion vector based on the representative motion vector and the representative location information, determining a motion vector of a current sub-block included in the current block, based on location information of the current sub-block and the parameter, and predicting the current block based on the motion vector of the current sub-block wherein the representative motion vector is determined based on the same motion vector, and the representative location information indicates coordinates that are determined based on the at least two neighboring sub-blocks.
