Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demand for storage capacity due to improved quality and resolution of digital media files necessitates more efficient compression methods to optimize storage and transmission requirements.
Innovation Solution
A system and method for compressing digital media files by identifying groups of images with similarity characteristics, using a base image to compress similar features among the group through image processing techniques such as difference algorithms and motion estimation, and storing compressed images with corresponding header information for efficient storage and decompression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If image resolution and quality are improved, then image quality is improved, but storage capacity requirements increase
Solution Approach 1:
The patent merges multiple similar images into a single compressed representation by identifying common features and storing only the differences. This combining approach reduces the total storage capacity needed while preserving the quality of individual images, directly resolving the contradiction between maintaining image quality and reducing storage requirements
Solution Approach 2:
The patent creates a universal base image that serves multiple functions - it acts as the foundation for multiple similar images, allowing efficient storage and retrieval of any image in the group. This multi-functional approach enables high-quality image storage with reduced capacity requirements
2Quantity of substance
If compression is applied to reduce storage needs, then storage efficiency is improved, but image quality may deteriorate
Solution Approach 1:
The patent applies local quality by storing only the specific differences between similar images rather than compressing entire images uniformly. This selective compression approach maintains high image quality in critical areas while achieving efficient storage through targeted compression of only the varying portions
Solution Approach 2:
The patent uses partial action by compressing only the difference portions of images rather than applying full compression to entire images. This partial compression strategy maintains image quality by preserving the base image in full quality while only compressing the minimal necessary difference data
3Quantity of substance
If groups of similar images are compressed using a base image, then storage capacity is optimized, but processing complexity increases
Solution Approach 1:
The patent segments the compression process into distinct phases: identifying similar images, selecting a base image, calculating differences, and storing compressed data. This segmentation of the processing workflow reduces overall complexity by breaking down the complex task into manageable, systematic steps

AI summary
The present disclosure relates generally to a system and method for file compression. More specifically, the disclosure introduces to a method for file compression wherein a group of files is identified by comparing a plurality of similarity characteristics. The group of files may then be compressed relative to at least one base file to improve compression efficiency.
