METHOD FOR DECODER-SIDE MOTION VECTOR DERIVATION USING SPATIAL CORRELATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 18746839 titled 'METHOD FOR DECODER-SIDE MOTION VECTOR DERIVATION USING SPATIAL CORRELATION

Simplified Explanation: The patent application describes a method for deriving motion vectors on the decoder side using spatial correlation to minimize discontinuities at block boundaries in video coding.

  • Utilizes spatial correlation for decoder-side motion vector derivation
  • Minimizes discontinuities at block boundaries in video coding
  • Derives motion vectors by considering spatial correlation with surrounding blocks
  • Overcomes disadvantages of per-block motion prediction
  • Considers spatial correlation rather than just the cost of current and prediction blocks

Potential Applications: 1. Video compression technology 2. Streaming services 3. Virtual reality applications 4. Surveillance systems 5. Video conferencing platforms

Problems Solved: 1. Discontinuities at block boundaries in video coding 2. Inaccurate motion prediction on a per-block basis 3. Lack of spatial correlation consideration in motion vector derivation

Benefits: 1. Improved video quality 2. Enhanced compression efficiency 3. Reduced artifacts in video streams 4. Better motion compensation accuracy 5. Enhanced user experience in video applications

Commercial Applications: The technology can be utilized in various industries such as video streaming services, surveillance systems, video conferencing platforms, and virtual reality applications to improve video quality, compression efficiency, and overall user experience.

Questions about the Technology: 1. How does the spatial correlation-based motion vector derivation improve video coding? 2. What are the specific advantages of considering spatial correlation in motion vector derivation?


Original Abstract Submitted

A method for decoder-side motion vector derivation utilizes a spatial correlation. A video coding method and apparatus minimize discontinuities at block boundaries, in order to overcome disadvantages of motion prediction that performs motion compensation on a per block basis. The video coding method and the apparatus derive, during decoder-side motion vector derivation, motion vectors by taking into account spatial correlation of the current block with surrounding blocks rather than deriving motion vectors by considering only the cost of a current and prediction block.
