VIDEO DECODING METHOD AND APPARATUS, AND VIDEO ENCODING METHOD AND APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240380899 titled 'VIDEO DECODING METHOD AND APPARATUS, AND VIDEO ENCODING METHOD AND APPARATUS

Simplified Explanation: This patent application describes a method and apparatus for determining if a slice containing an adjacent pixel at the upper-left or lower-right side of a current pixel is different from a slice containing the current pixel. If the adjacent pixel slice is different, the value of the adjacent pixel is used to correct the current pixel value through an adaptive loop filter during video encoding and decoding processes.

• Method and apparatus for determining differences between adjacent pixel slices in video encoding/decoding.
• Correction of current pixel value using adjacent pixel value through an adaptive loop filter.
• Encoding/decoding of current block with corrected pixel values.

Potential Applications: This technology can be applied in video encoding and decoding processes to improve image quality by correcting pixel values based on adjacent pixels.

Problems Solved: 1. Ensuring consistency in pixel values between adjacent slices. 2. Enhancing image quality through adaptive correction methods.

Benefits: 1. Improved image quality in video encoding/decoding. 2. Enhanced accuracy in pixel value correction. 3. Consistent visual output in video processing.

Commercial Applications: Potential commercial uses include video streaming services, video editing software, and digital media production companies. This technology can enhance the quality of video content and improve user experience.

Prior Art: Prior art related to this technology may include research on adaptive loop filters in video processing and methods for correcting pixel values in image encoding/decoding.

Frequently Updated Research: Stay updated on advancements in video encoding/decoding technologies, adaptive loop filters, and image processing methods to enhance the application of this technology.

Questions about Video Encoding and Decoding: 1. How does this technology improve image quality in video processing? 2. What are the key benefits of using adaptive loop filters in video encoding and decoding?

Original Abstract Submitted

in a video encoding and decoding process, provided are a method and apparatus for determining whether a slice including an adjacent pixel located at the upper-left or lower-right side of a current pixel from among adjacent pixels used for an adaptive loop filter of the current pixel is different from a slice including the current pixel, when the slice including the adjacent pixel at the upper-left or lower-right location is different from the slice including the current pixel, determining a value of the adjacent pixel located at the upper-left or lower-right side as a value of a closest pixel in a horizontal direction of the adjacent pixel located at the upper-left or lower-right side from among pixels included in the slice including the current pixel, determining an adaptive loop filter including a filter coefficient for the current pixel and the adjacent pixels based on values of the current pixel and the adjacent pixels, correcting the value of the current pixel by using the values of the adjacent pixels, by applying the adaptive loop filter to the current pixel, and encoding/decoding a current block including the current pixel.
