Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual parameter setting is used to adjust special effect intensity in shielded areas, then processing precision can be controlled, but operation complexity increases and real-time adjustment becomes difficult
Solution Approach 1:
The system automatically detects shielded areas and adjusts special effect parameters without requiring manual user input. The processing device autonomously identifies regions where objects shield the background and automatically modifies special effect intensity in those areas, eliminating the need for users to manually set complex parameters while maintaining precise control over effect application.
2Productivity
If real-time special effect adjustment is implemented, then video processing efficiency improves, but computational complexity and processing time increase
Solution Approach 1:
The system divides the video frame into multiple regions, identifying shielded areas versus non-shielded areas. By segmenting the image processing task into detecting shielded regions and then applying effects only to those regions, the system achieves real-time processing efficiency while reducing overall computational complexity compared to processing every pixel uniformly.
Solution Approach 2:
The system performs preliminary detection of shielded areas before applying special effects. By pre-identifying which regions require effect adjustment based on object shielding, the system can efficiently process only the necessary areas in real-time, avoiding unnecessary computational overhead while maintaining high processing speed.
3Manufacturing precision
If special effect maps are automatically modified based on shielded areas, then effect precision improves, but processing time and computational resources increase
Solution Approach 1:
The system applies different processing quality to different regions of the video frame. Shielded areas receive automatic special effect modification with high precision, while non-shielded areas are processed differently or not at all. This local quality approach achieves precise effect application in critical regions without uniformly processing the entire image, thereby reducing overall processing time.
