Hybrid Motion Image Compression via Inter-Frame Transformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing systems face challenges in accurately transmitting and compressing image streams from moving imaging platforms, such as airborne or space-based systems, due to bandwidth limitations and compression errors caused by relative motion-induced changes in image data.
Innovation Solution
A system and method that determine and store coefficients for transformations associated with inter-frame changes caused by relative motion, allowing for the correction and storage of these changes in image metadata, which are then used to transform images before compression, thereby reducing errors and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If images are compressed to reduce bandwidth requirements, then transmission efficiency is improved, but compression errors are introduced and original imagery cannot be accurately recreated
Solution Approach 1:
The system performs preliminary motion compensation by transforming images to correct for expected inter-frame changes caused by relative motion between the scene and imaging platform. This preliminary action stabilizes the image data before compression, allowing standard compression algorithms to achieve higher accuracy without introducing as many errors, thus resolving the contradiction between transmission efficiency and compression accuracy
2Productivity
If existing compression systems are used to transmit imagery, then bandwidth limitations are addressed, but the system complexity increases due to additional processing requirements
Solution Approach 1:
The patent introduces an intermediary transformation step that corrects motion-induced distortions before compression. This intermediary process (motion compensation transformation) acts as a bridge between the raw image data and the compression algorithm, allowing standard compression systems to achieve better performance without requiring fundamentally new complex processing techniques, thus managing the complexity while improving bandwidth utilization
