DEBLOCKING USING SUB-PEL MOTION VECTOR THRESHOLD - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240187583 titled 'DEBLOCKING USING SUB-PEL MOTION VECTOR THRESHOLD
Simplified Explanation
The patent application describes a method for deblocking at least one boundary of a coding unit in a video picture, where the first and second sides of the coding unit use the same reference picture.
- Obtaining motion vector components on the first and second sides of the coding unit.
- Determining if the absolute difference between the motion vector components is equal to or larger than a predetermined threshold.
- Applying deblocking to the vertical or horizontal boundary between the first and second sides if the absolute difference is equal to or larger than the threshold.
Potential Applications
This technology can be applied in video coding and compression systems to improve the visual quality of video pictures by reducing artifacts at coding unit boundaries.
Problems Solved
This technology solves the problem of visible artifacts at coding unit boundaries in video pictures, which can degrade the overall visual quality of the video.
Benefits
The benefits of this technology include improved visual quality of video pictures, enhanced compression efficiency, and a more seamless viewing experience for users.
Potential Commercial Applications
Potential commercial applications of this technology include video streaming services, video conferencing platforms, digital video recorders, and video editing software.
Possible Prior Art
One possible prior art for this technology is the use of deblocking filters in video coding standards such as H.264/AVC and H.265/HEVC to reduce artifacts at block boundaries.
What are the computational complexities of implementing this method in real-time video processing systems?
The computational complexities of implementing this method in real-time video processing systems depend on factors such as the resolution of the video, the number of coding units, and the processing power of the system. Implementing deblocking at coding unit boundaries may require additional computational resources, which could impact real-time performance.
How does this method compare to existing deblocking techniques in terms of computational efficiency and visual quality improvement?
This method offers a balance between computational efficiency and visual quality improvement by selectively applying deblocking at coding unit boundaries based on motion vector differences. Compared to existing deblocking techniques, this method may provide a more targeted approach to artifact reduction while minimizing computational overhead.
Original Abstract Submitted
a method for deblocking at least one boundary of a coding unit, wherein the boundary forms a first side and a second side of the coding unit, wherein a video picture comprises the coding unit, and wherein the first and second sides use a same reference picture. the method includes obtaining a first motion vector component in the first side; obtaining a second motion vector component in the second side; determining whether an absolute difference between the first motion vector component and the second motion vector component is equal to or larger than a predetermined threshold that is less than 1 sample; and as a result of determining that the absolute difference between the first motion vector component and the second motion vector component is equal to or larger than the predetermined threshold, applying deblocking to the vertical or horizontal boundary between the first side and the second side.
