Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current compression techniques prioritize high compression ratios over processing latency, leading to inefficiencies in real-time image and video data analysis, particularly in mobile and distributed contexts where low latency and data integrity are critical.
Innovation Solution
The system compresses digital image data by independently compressing pixel groups, using comparison values to replace pixel data, allowing for dynamic adjustment of compression ratios based on latency and throughput requirements, and enabling parallel processing to minimize overall latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If large blocks of data are used for compression analysis to achieve higher compression ratios, then compression efficiency is improved, but processing latency and memory requirements increase
Solution Approach 1:
The image data is divided into multiple independent pixel groups (e.g., 16x16 or 32x32 pixel blocks) that can be compressed and transmitted independently. This segmentation allows the system to process smaller data units in parallel, reducing the waiting time for complete block reception while maintaining compression efficiency through selective application of compression algorithms on each segment.
Solution Approach 2:
The system dynamically adjusts the compression strategy based on latency requirements. For time-sensitive applications, it uses smaller pixel groups with faster compression algorithms; for less time-sensitive applications, it can use larger blocks for higher compression ratios. This dynamic adaptation allows optimization of the trade-off between compression ratio and processing latency.
2Loss of information
If large blocks of data are used for compression analysis to achieve higher compression ratios, then compression efficiency is improved, but memory resources required increase
Solution Approach 1:
By segmenting the image into smaller independent pixel groups, the system reduces the memory buffer required to hold complete large blocks before compression can begin. Each small pixel group can be processed with minimal memory overhead, enabling deployment on devices with limited memory resources while maintaining acceptable compression ratios.
3Loss of information
If compression processes wait for entire blocks of data before processing to maximize compression, then compression ratio is improved, but processing speed decreases
Solution Approach 1:
The patent segments the image data into independent pixel groups that can be compressed as soon as they are received, without waiting for the entire image or large blocks. This enables pipelined processing where compression of early segments begins immediately, improving processing speed while maintaining compression efficiency on each segment.
Solution Approach 2:
The system performs preliminary compression on received pixel groups before the complete image data is available. By starting compression on partial data immediately rather than waiting for complete blocks, the system reduces overall processing time while still achieving effective compression on the transmitted portions.
4Loss of information
If complex compression algorithms are used to achieve higher compression ratios, then data transmission efficiency is improved, but processing complexity and latency increase
Solution Approach 1:
The system dynamically selects compression algorithm complexity based on application requirements. For real-time applications with strict latency constraints, it uses simpler, faster compression algorithms on small pixel groups. For applications where bandwidth is the primary constraint, it can employ more complex algorithms. This dynamic selection optimizes the balance between compression ratio and processing complexity.
