Engineering Contradiction Analysis
1Quantity of substance
If 3-D image data is compressed to reduce size, then storage efficiency is improved, but image quality deteriorates due to distortions such as decreased sharpness and color shifting
Solution Approach 1:
The patent applies different compensation strategies to different regions of the image based on their importance. High-pass filtering is applied selectively to enhance details in regions where compression artifacts are most prominent, while maintaining original data in regions where compression has already preserved quality. This local differentiation allows quality improvement without requiring full decompression of entire images.
Solution Approach 2:
The system performs preliminary detection to identify compression artifacts and regions requiring compensation before final image rendering. By detecting the dependent frame and comparing it with the base frame in advance, the system pre-determines which regions need enhancement, allowing targeted compensation that prevents quality degradation before it affects the final output.
2Productivity
If different compression rates are applied to base and dependent frames, then coding efficiency is improved, but visual consistency deteriorates due to differences in image details between frames
Solution Approach 1:
The system uses the base frame as a reference feedback signal to compensate for the dependent frame. By continuously comparing the dependent frame against the base frame and applying high-pass filtering to enhance differences, the system creates a feedback loop that maintains visual consistency between frames while preserving the efficiency benefits of differential compression.
Solution Approach 2:
The patent introduces an intermediary compensation process that mediates between the base frame and dependent frame. This intermediary step involves detecting the dependent frame, comparing it with the base frame, and applying selective high-pass filtering to create a compensated version that bridges the quality gap without requiring full decompression of either frame.
