Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If existing face image processing techniques are used, then the processing speed is maintained, but the submalar triangle filling accuracy and naturalness deteriorate
Solution Approach 1:
The face image processing is segmented into distinct modules: face key point detection, submalar triangle region determination, and color filling. This segmentation allows each module to be optimized independently, improving filling accuracy through precise region localization while managing complexity through modular design.
Solution Approach 2:
The method performs preliminary detection of face key points and determination of the submalar triangle region before executing the color filling operation. This preliminary action ensures accurate positioning and boundary definition, directly improving filling precision by establishing the target region with high accuracy before the actual filling process.
2Device complexity
If simple filling methods are used, then the processing complexity is reduced, but the naturalness and harmony of the submalar triangle appearance deteriorates
Solution Approach 1:
The color filling operation is applied locally to the specifically determined submalar triangle region rather than uniformly across the entire face. This local quality approach ensures that filling parameters and color characteristics are optimized for the specific anatomical region, producing natural-looking results that harmonize with surrounding facial features while maintaining controlled processing complexity.
Solution Approach 2:
The method employs color filling techniques that adjust the color parameters within the submalar triangle region to achieve a natural, full appearance. By carefully controlling color changes and blending them with adjacent regions, the method enhances the visual naturalness and harmony of the treated area without requiring overly complex processing algorithms.
