SYSTEM AND METHOD FOR REDUCING BLOCKING ARTIFACTS AND PROVIDING IMPROVED CODING EFFICIENCY - A simplified explanation of the abstract
This abstract first appeared for US patent application 18386548 titled 'SYSTEM AND METHOD FOR REDUCING BLOCKING ARTIFACTS AND PROVIDING IMPROVED CODING EFFICIENCY
Simplified Explanation:
This patent application describes a system and method for reducing blocking artifacts and improving coding efficiency by evaluating the smoothness of signals at coding boundaries and applying filtering based on the signal characteristics.
- Signals are evaluated at coding boundaries to determine the smoothness of the transition.
- A boundary threshold difference is established to identify natural or intended boundaries.
- Filtering is applied to boundaries with differences below the threshold to reduce artifacts.
- The system evaluates signal ramps to determine the appropriate level of filtering.
- Weak filtering is applied to reduce artifacts without distorting signal ramps.
Key Features and Innovation:
- Evaluation of relative smoothness of signals at coding boundaries.
- Establishment of a boundary threshold difference for filtering.
- Assessment of signal ramps for appropriate filtering levels.
- Implementation of weak filtering to reduce artifacts without distorting signals.
Potential Applications:
This technology can be applied in video coding, image processing, and multimedia compression systems to improve the quality of encoded content.
Problems Solved:
This technology addresses the issue of blocking artifacts in compressed multimedia content and enhances coding efficiency by applying targeted filtering at coding boundaries.
Benefits:
- Improved visual quality of compressed multimedia content.
- Enhanced coding efficiency leading to reduced file sizes.
- Minimization of blocking artifacts for a better viewing experience.
Commercial Applications:
Potential commercial applications include video streaming services, video conferencing platforms, and multimedia content distribution networks.
Questions about the Technology: 1. How does this technology improve the quality of compressed multimedia content? 2. What are the key factors considered when determining the appropriate level of filtering at coding boundaries?
Original Abstract Submitted
A system and method of reducing blocking artifacts and providing enhanced coding efficiency based, as least in part, upon evaluation of relative smoothness of signals at a coding boundary. In some embodiments, a boundary threshold difference can be established beyond which it is determined that the difference is representative of a natural or intended boundary and filtering can be applied to those boundaries having differences below the boundary threshold difference. In some further embodiments, the ramps of the signal across the boundary can be evaluated to determine whether weak or strong filtering might be appropriate. In some further embodiments, weak filtering can be performed that reduces blocking artifacts, improves coding efficiency, but does not distort ramp signals across the boundary.
