SYSTEMS AND METHODS FOR VIDEO DECODING WITH PARTIAL-BLOCK DEBLOCKING FILTERING FOR USE BY CONSTRAINED DIRECTIONAL ENHANCEMENT FILTER - A simplified explanation of the abstract
This abstract first appeared for US patent application 17875317 titled 'SYSTEMS AND METHODS FOR VIDEO DECODING WITH PARTIAL-BLOCK DEBLOCKING FILTERING FOR USE BY CONSTRAINED DIRECTIONAL ENHANCEMENT FILTER
Simplified Explanation
The abstract describes a video decoding system that applies a deblocking (DB) filter to sub-blocks of video data to generate a DB-filtered plurality of sub-blocks. It also applies the DB filter to one or more lines of pixels in an additional sub-block to generate a DB-filtered portion of the additional sub-block. The additional sub-block is adjacent to at least one of the plurality of sub-blocks. The system then applies a constrained directional enhancement filter (CDEF) to the DB-filtered plurality of sub-blocks and the DB-filtered portion of the additional sub-block to generate a CDEF-filtered plurality of sub-blocks.
- The system applies a deblocking filter to sub-blocks of video data.
- It applies the deblocking filter to one or more lines of pixels in an additional sub-block.
- The additional sub-block is adjacent to at least one of the sub-blocks.
- The system then applies a constrained directional enhancement filter to the deblocked sub-blocks and the deblocked portion of the additional sub-block.
Potential applications of this technology:
- Video streaming platforms can use this technology to improve the quality of video playback by reducing blockiness and artifacts.
- Video compression algorithms can benefit from this technology to enhance the visual quality of compressed videos.
- Video editing software can utilize this technology to enhance the clarity and sharpness of video footage.
Problems solved by this technology:
- Blockiness and artifacts in video playback can be reduced, resulting in a smoother and more visually appealing viewing experience.
- Compressed videos can have improved visual quality, making them more enjoyable to watch.
- Video footage can be enhanced to improve the clarity and sharpness, providing better visual representation.
Benefits of this technology:
- Improved video quality leads to a better user experience for video streaming platforms and video playback in general.
- Enhanced visual quality of compressed videos can attract more viewers and increase user satisfaction.
- Clearer and sharper video footage can be beneficial for various applications such as video editing, surveillance, and medical imaging.
Original Abstract Submitted
Video decoding systems and techniques are described. The decoder applies a deblocking (DB) filter to the plurality of sub-blocks of a block of video data to generate a DB-filtered plurality of sub-blocks. The decoder applies the DB filter to one or more lines (e.g., columns) of pixels in an additional sub-block of the block to generate a DB-filtered portion of the additional sub-block. The one or more lines of pixels in the additional sub-block are filtered without filtering an entirety of the additional sub-block using the DB filter. The additional sub-block is adjacent to at least one of the plurality of sub-blocks. The decoder applies a constrained directional enhancement filter (CDEF) to the DB-filtered plurality of sub-blocks and the DB-filtered portion of the additional sub-block to generate a CDEF-filtered plurality of sub-blocks.
