ADAPTIVE LOOP FILTER - A simplified explanation of the abstract
This abstract first appeared for US patent application 18652710 titled 'ADAPTIVE LOOP FILTER
The abstract describes a method of controlling an Adaptive Loop Filter by selecting alternative chroma filters for coding tree blocks in a slice of image data.
- The method involves obtaining data indicating available alternative chroma filters for a slice.
- It also involves obtaining an alternative filter index for a coding tree block in the slice.
- The selected alternative chroma filter is then used to filter chroma image data in the coding tree block.
Potential Applications: - Video coding and compression technologies - Image processing applications - Multimedia content creation
Problems Solved: - Enhancing image quality in video coding - Optimizing chroma filtering in coding tree blocks - Improving compression efficiency
Benefits: - Higher quality video encoding - More efficient compression algorithms - Enhanced visual experience for viewers
Commercial Applications: Title: "Enhanced Video Compression Technology for Multimedia Applications" This technology can be used in: - Video streaming services - Video conferencing platforms - Digital media production companies
Prior Art: Researchers can explore existing patents related to adaptive loop filters, chroma filtering, and video compression technologies to understand the prior art in this field.
Frequently Updated Research: Researchers can stay updated on advancements in video coding standards like HEVC (High Efficiency Video Coding) and VVC (Versatile Video Coding) to see how this technology aligns with industry trends.
Questions about Adaptive Loop Filter Technology: 1. How does this method improve the efficiency of chroma filtering in video coding? 2. What are the key considerations when selecting alternative chroma filters for coding tree blocks?
Original Abstract Submitted
A method of controlling an Adaptive Loop Filter comprises obtaining for a slice containing one or more coding tree blocks, data indicating a number of available alternative chroma filters, obtaining for a coding tree block in the slice, an alternative filter index identifying one of the available alternative chroma filters, and selecting the alternative chroma filter identified by the index to filter chroma image data in the coding tree block.
