Digital Image Metadata Embedding for Procedure Reconstruction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sending multiple images, including original and processed images, increases data size and transmission time, and sending only processed images without the original image prevents the receiver from understanding the processing procedures used to generate them.
Innovation Solution
A method that integrates a first digital image into a second digital image, generates codes representing the integration procedures and image retrieval information, and embeds these codes as metadata into a file containing the second digital image, allowing the receiver to reconstruct and display the integrated image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple images (original and processed) are sent, then the receiver can understand the processing procedures and have all image versions, but the data size and transmission time increase
Solution Approach 1:
The patent extracts only the essential processing procedure information and embeds it as metadata in the processed image file, rather than transmitting the entire original image file. This extraction approach transmits only the necessary information (processing procedures and original image identification) while avoiding redundant data transmission.
Solution Approach 2:
The patent creates a lightweight copy of the processing information in the form of metadata embedded in the processed image. Instead of copying the entire original image, it copies only the essential processing procedure data, which can then be used to reproduce or understand the processing that was applied.
2Quantity of substance
If only processed images are sent without original images, then data size is reduced, but the receiver cannot understand the processing procedures used
Solution Approach 1:
The patent performs preliminary action by embedding the processing procedure information (metadata) into the processed image file before transmission. This ensures that when the processed image is received, the processing information is already available, eliminating the need to transmit the original image separately.
Solution Approach 2:
The patent introduces metadata as an intermediary that carries the processing procedure information. This metadata acts as a bridge between the processed image and the original image, containing references and instructions that allow the receiver to understand or reproduce the processing without having direct access to the original image file.
3Productivity
If processing procedure information is embedded in metadata, then data transmission efficiency is improved, but the file structure becomes more complex
Solution Approach 1:
The patent uses standard metadata fields that are universally supported by image processing systems. By leveraging existing, widely-compatible metadata structures rather than creating proprietary formats, the solution achieves multi-functionality - the same metadata structure can store processing information while remaining compatible with various software platforms and maintaining relatively simple file structures.
Data Source
AI summary
A first digital image is integrated into a second digital image to generate a third digital image. A first code representing the procedures performed to integrate the first digital image into the second digital image is generated. A second code representing information for retrieving the first digital image is generated. The first code and the second code are embedded as metadata into a file that contains the second digital image.
