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 20240380897 titled 'VIDEO DECODING METHOD AND APPARATUS, AND VIDEO ENCODING METHOD AND APPARATUS

The abstract describes a method and apparatus for determining whether 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 in a video encoding and decoding process.

• Method and apparatus for determining differences between adjacent pixels for an adaptive loop filter.
• Value of the adjacent pixel is determined as the value of the closest pixel in a horizontal direction.
• Adaptive loop filter with filter coefficients based on values of current and adjacent pixels.
• Correction of the current pixel value using values of adjacent pixels.
• Encoding/decoding of a current block including the current pixel.

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.
