MULTI-FEATURE SAMPLE OFFSET FILTERING SYSTEM FOR VIDEO CODING AND DECODING - A simplified explanation of the abstract

This abstract first appeared for US patent application 17979025 titled 'MULTI-FEATURE SAMPLE OFFSET FILTERING SYSTEM FOR VIDEO CODING AND DECODING

Simplified Explanation

The patent application describes a filtering system for video coders and decoders. It includes a feature detector, an offset calculator, and a filter.

• The feature detector analyzes reconstructed video data and identifies features in the color component of the source video.
• The offset calculator uses the feature identification data to calculate a filter offset.
• The filter applies the filter offset to the reconstructed samples and produces filtered samples.

Potential Applications

This technology can be applied in various video coding and decoding systems, including:

• Video streaming platforms
• Video conferencing systems
• Video editing software
• Video surveillance systems

Problems Solved

The filtering system addresses the following problems in video coding and decoding:

• Inaccurate filtering due to the use of filtering offsets that are not based on analysis of recovered video data.
• Inefficient operations of video coder/decoder filtering systems.
• Poor quality of reconstructed video data.

Benefits

The filtering system offers several benefits:

• Improved accuracy of filtering by selecting filtering offsets based on analysis of recovered video data in a common color plane.
• Enhanced efficiency of video coder/decoder filtering systems.
• Higher quality of reconstructed video data.

Original Abstract Submitted

A filtering system for video coders and decoders is disclosed that includes a feature detector having an input for samples reconstructed from coded video data representing a color component of source video, and having an output for data identifying a feature recognized therefrom, an offset calculator having an input for the feature identification data from the feature detector and having an output for a filter offset, and a filter having an input for the filter offset from the offset calculator and an input for the reconstructed samples, and having an output for filtered samples. The filtering system is expected to improve operations of video coder/decoder filtering systems by selecting filtering offsets from analysis of recovered video data in a common color plane as the samples that will be filtered.
