Image Slice Signaling with Flags for High-Resolution Compression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demand for high-resolution and high-quality images has led to a need for more efficient image compression techniques to reduce transmission and storage costs.
Innovation Solution
The method involves obtaining image information including partitioning information from a bitstream, deriving slices within a current picture based on this information, and reconstructing the picture from these slices, using specific flags to indicate the presence of subpicture information and whether each subpicture includes only one slice.

Engineering Contradiction Analysis
1Manufacturing precision
If image data is transmitted using conventional wired/wireless broadband lines and stored using existing storage media, then high-resolution and high-quality images can be transmitted and stored, but transmission cost and storage cost increase
Solution Approach 1:
The patent divides the image into multiple slices, where each slice can be independently encoded and transmitted. This segmentation allows for more efficient compression while maintaining overall image quality, thereby reducing transmission costs without sacrificing manufacturing precision (image quality).
Solution Approach 2:
The patent changes the encoding parameters by introducing flags (first flag for subpicture information presence, second flag for single slice per subpicture) that allow adaptive compression. This enables optimization of the compression ratio while preserving image quality, addressing the contradiction between transmission cost and image quality.
2Manufacturing precision
If image data is transmitted using conventional wired/wireless broadband lines and stored using existing storage media, then high-resolution and high-quality images can be transmitted and stored, but transmission cost and storage cost increase
Solution Approach 1:
By segmenting the image into slices with independent encoding capabilities, the patent achieves better compression efficiency. This reduces the amount of data that needs to be stored while maintaining image quality, thereby reducing storage costs without compromising manufacturing precision.
Solution Approach 2:
The patent modifies encoding parameters by using flags to indicate subpicture information presence and slice configuration. This enables optimized compression that reduces data volume for storage while preserving image quality, thus addressing the contradiction between storage cost and image quality.
3Productivity
If partitioning information is signaled using flags, then compression efficiency is improved, but bitstream complexity increases
Solution Approach 1:
The patent changes the signaling parameters by using simple flag values (0 or 1) to convey partitioning information. This approach improves compression efficiency through better partitioning while keeping the bitstream relatively simple, as flags are more compact than detailed partitioning data. The first flag indicates subpicture information presence, and the second flag indicates single slice per subpicture, providing efficient compression without excessive complexity.

AI summary
A method by which a decoding device decodes an image, according the present disclosure, comprises a flag related to whether there is sub-picture information and a flag related to whether a sub-picture includes a single slice, wherein the flag related to whether there is sub-picture information corresponds to a value of 0, and the flag related to whether the sub-picture includes the single slice corresponds to a value of 1.
