METHOD AND APPARATUS FOR ENCODING OR DECODING VIDEO DATA WITH SUB-PIXEL MOTION VECTOR REFINEMENT - A simplified explanation of the abstract
This abstract first appeared for US patent application 18514157 titled 'METHOD AND APPARATUS FOR ENCODING OR DECODING VIDEO DATA WITH SUB-PIXEL MOTION VECTOR REFINEMENT
Simplified Explanation
The patent application describes a method and device for encoding or decoding video data, specifically focusing on a motion vector derivation mode called frame-rate up conversion mode (FRUC) merge mode. This mode includes a refinement step to improve the accuracy of motion vectors at the sub-pixel level by evaluating different sub-pixel positions around the obtained motion vector.
- The invention aims to enhance the refinement step in the FRUC merge mode to improve coding efficiency.
- It considers the characteristics of the matching type and/or the signal inside the templates to optimize the refinement process.
Potential Applications
- Video encoding and decoding systems
- Multimedia streaming services
- Video surveillance technology
Problems Solved
- Inaccurate motion vector estimation in video encoding
- Suboptimal coding efficiency in video processing
- Limited accuracy in sub-pixel motion estimation
Benefits
- Improved video quality in encoding and decoding processes
- Enhanced coding efficiency for better compression
- More accurate motion vector estimation for smoother video playback
Original Abstract Submitted
A method and a device for encoding or decoding video data. It concerns more particularly the encoding according to a particular encoding mode using a decoder side motion vector derivation mode referenced as frame-rate up conversion mode or FRUC mode. In FRUC merge mode, the derivation process comprises a refinement step to increase the accuracy of the obtained motion vector at the sub-pixel level. This process involves the evaluation of different sub-pixel position around the obtained motion vector according to different patterns. The present invention has been devised to improve the known refinement step. It aims at improving the coding efficiency by considering the characteristics of the matching type and/or the signal inside the templates.
