Improved Prediction with Local Illumination Compensation - A simplified explanation of the abstract
This abstract first appeared for US patent application 18513101 titled 'Improved Prediction with Local Illumination Compensation
Simplified Explanation
The abstract describes a method for encoding blocks in a picture using local illumination compensation (LIC) to improve image quality. The method involves determining a current block and candidate reference block templates from the same picture, and then making a prediction of the current block based on differences between the current block and the reference block.
- Determining current block and candidate reference block templates from the same picture
- Using an indication of whether to use local illumination compensation (LIC) on the current block
- Determining differences between the current block and candidate reference blocks
- Selecting a reference block based on the differences
- Making a prediction of the current block based on the indication and the difference between the current block and the reference block
Potential Applications
This technology could be applied in image and video compression algorithms to improve image quality and reduce file sizes.
Problems Solved
This technology helps address issues related to image quality degradation during compression and transmission of images and videos.
Benefits
The use of local illumination compensation (LIC) can enhance image quality by compensating for variations in illumination across different parts of an image.
Potential Commercial Applications
One potential commercial application of this technology is in the development of advanced video compression software for streaming services.
Possible Prior Art
One possible prior art for this technology could be existing image and video compression algorithms that aim to improve image quality during encoding and decoding processes.
Unanswered Questions
How does this technology compare to existing image compression techniques?
This article does not provide a direct comparison to existing image compression techniques in terms of performance, efficiency, or image quality improvement.
What are the potential limitations of using local illumination compensation (LIC) in image encoding?
The article does not address any potential limitations or challenges that may arise from implementing LIC in image encoding processes.
Original Abstract Submitted
A current block to be encoded and candidate reference block templates may be determined from the same picture. A bitstream may include an indication of whether to use local illumination compensation (LIC) on the current block. Based on the indication, differences between the current block and the candidate reference blocks may be determined. Based on the differences, a reference block may be determined, and a prediction of the current block may be made based on the indication and the difference between the current block and the reference block.
