LOCAL ILLUMINATION COMPENSATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 18240950 titled 'LOCAL ILLUMINATION COMPENSATION
The abstract describes processing circuitry for video decoding that applies local illumination compensation (LIC) to a current block in a current picture based on coded information from a video bitstream.
- The processing circuitry derives parameters of an LIC model using templates of the current block and a reference block in a reference picture, pointed based on a motion vector.
- The first template includes reconstructed neighboring samples above and left to the current block, while the second template includes collocated samples to the subset of the reconstructed neighboring samples.
- The processing circuitry applies the LIC model to the current block according to the reference block to generate compensated samples.
Potential Applications: - Video decoding and processing technologies - Image enhancement and correction in video streaming services - Real-time video processing for broadcasting and surveillance systems
Problems Solved: - Improving image quality by compensating for local illumination variations - Enhancing visual clarity and detail in video content
Benefits: - Enhanced image quality and visual appeal in videos - Improved accuracy in compensating for local illumination variations - Real-time processing capabilities for seamless video playback
Commercial Applications: Title: Advanced Video Processing Technology for Enhanced Image Quality This technology can be utilized in: - Video streaming platforms for improved user experience - Surveillance systems for clearer video footage - Broadcasting companies for high-quality content delivery
Questions about the technology: 1. How does the processing circuitry determine the parameters of the LIC model? - The processing circuitry derives parameters using templates of the current block and a reference block in a reference picture. 2.

Original Abstract Submitted
Processing circuitry for video decoding receives coded information of a current block in a current picture from a coded video bitstream, the coded information is indicative of applying local illumination compensation (LIC) on the current block in the current picture. The processing circuitry derives, parameters of an LIC model, according to a first template of a current block and a second template of a reference block in a reference picture. The reference block is pointed based on a motion vector for the current block. The first template includes a subset of reconstructed neighboring samples that are above and left to the current block, and the second template includes collocated samples to the subset of the reconstructed neighboring samples. The processing circuitry applies the LIC model on the current block according to the reference block to generate compensated samples of the current block.
