Scalable Image Reconstruction with Base and Extension Blocks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scalable encoding systems face challenges in efficiently managing information storage, transmission, and decoder processing, particularly in handling errors and providing up-to-date configuration for accurate and reliable signal reconstruction across varying decoder capabilities and bandwidths.
Innovation Solution
A method involving a configuration block and an extension configuration block is used to reconstruct images at multiple quality levels, where the extension block adjusts or modifies the configuration signaled by the primary block, allowing decoders to perform predetermined actions for enhanced image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If configuration information is transmitted frequently to ensure up-to-date reconstruction parameters, then reconstruction accuracy is improved, but transmission bandwidth and processing load increase
Solution Approach 1:
The configuration information is segmented into a base configuration block containing essential parameters and an optional extension configuration block containing additional or updated parameters. This segmentation allows the decoder to process only the necessary configuration data for accurate reconstruction without requiring the transmission of complete configuration information, thereby reducing bandwidth consumption while maintaining reconstruction accuracy.
2Adaptability or versatility
If extension configuration blocks are added to provide flexible decoder control, then decoder adaptability is improved, but configuration processing complexity increases
Solution Approach 1:
The configuration system is designed to be dynamic through the optional extension configuration block that can be selectively applied based on decoder capabilities and requirements. The extension block allows the decoder to adapt its configuration dynamically without requiring a complete reconfiguration process, thereby enhancing flexibility while managing processing complexity through selective application rather than mandatory processing of all configuration data.
3Reliability
If configuration data is updated frequently to handle errors and unexpected information, then reconstruction reliability is improved, but processing time and computational load increase
Solution Approach 1:
The base configuration block is provided with essential reconstruction parameters in advance, enabling the decoder to perform basic reconstruction operations immediately. The extension configuration block contains additional parameters that can be applied when needed to handle errors or unexpected information. This preliminary provision of essential configuration data allows the decoder to operate reliably without requiring frequent complete updates, thereby reducing processing time while maintaining reconstruction reliability.

AI summary
A method (1200) is provided. A configuration block (1210) comprising a configuration value (1220) is obtained. The configuration block (1210) is useable to reconstruct a first representation of an image at a first level of quality in a tiered hierarchy having multiple levels of quality using a second representation of the image at the first level of quality. The second representation is based on a representation of the image at a second, lower level of quality in the tiered hierarchy. An extension configuration block (1240) comprising an extension configuration value (1250) is obtained. The configuration value (1220) and/or the extension configuration value (1250) is useable by a decoder to reconstruct the first representation of the image at the first level of quality.
