ENCODING METHOD AND APPARATUS THEREFOR, AND DECODING METHOD AND APPARATUS THEREFOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 17967352 titled 'ENCODING METHOD AND APPARATUS THEREFOR, AND DECODING METHOD AND APPARATUS THEREFOR
Simplified Explanation
The patent application describes a video decoding method that applies a deblocking filter to neighboring pixels next to the boundary of a current block. The method involves selecting a deblocking filter based on the pixel values of the neighboring pixels and the size of the current block, and then applying the selected filter to the neighboring pixels. The method includes multiple deblocking filters with different ranges of neighboring pixels for filtering.
- The video decoding method applies a deblocking filter to neighboring pixels adjacent to a block boundary.
- The method selects a deblocking filter from a set of filters based on the pixel values of the neighboring pixels and the size of the current block.
- The selected deblocking filter is then applied to the neighboring pixels.
- The set of deblocking filters includes three or more filters with different ranges of neighboring pixels for filtering.
Potential Applications
This technology can be applied in various video decoding systems and devices, including:
- Video streaming platforms and services
- Video playback software and applications
- Video compression and encoding systems
- Video conferencing and communication tools
Problems Solved
The video decoding method addresses the following problems:
- Block artifacts: By applying deblocking filters to neighboring pixels, the method reduces blocky artifacts that can occur at block boundaries in compressed video.
- Image quality degradation: The method helps to improve the overall visual quality of decoded videos by reducing visual distortions caused by block artifacts.
- Compression efficiency: By selectively applying deblocking filters based on pixel values and block size, the method optimizes the trade-off between compression efficiency and visual quality.
Benefits
The use of this video decoding method offers several benefits:
- Enhanced video quality: By effectively reducing block artifacts, the method improves the visual quality of decoded videos, providing a more enjoyable viewing experience.
- Improved compression efficiency: The selective application of deblocking filters based on pixel values and block size helps to maintain high compression efficiency while minimizing visual distortions.
- Versatility: The availability of multiple deblocking filters with different ranges allows for flexibility in adapting to various video content and block sizes.
Original Abstract Submitted
Provided is a video decoding method of applying a deblocking filter to neighboring pixels adjacent to a boundary of a current block, the video decoding method including selecting a deblocking filter to be applied to the neighboring pixels from among a plurality of deblocking filters according to pixel values of the neighboring pixels and a size of the current block, and applying the selected deblocking filter to the neighboring pixels, wherein the plurality of deblocking filters include three or more deblocking filters having different ranges of neighboring pixels to which deblocking filtering is applied.
