Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing image de-graying methods are used, then the processing can be performed, but the image effects are not good and do not meet user needs
Solution Approach 1:
The patent applies local quality by detecting feature regions (such as skin regions) and applying different de-graying strategies to different areas of the image. The method determines whether a region contains feature elements and adjusts processing parameters accordingly, allowing optimized de-graying effects for specific regions while maintaining overall image quality.
Solution Approach 2:
The patent changes processing parameters based on detected feature regions. When feature regions are detected, the method adjusts transmissivity values and de-graying intensities specifically for those regions. The system modifies parameters such as de-graying intensity and color adjustment based on the presence and characteristics of detected features.
2Measurement precision
If feature region detection is performed, then de-graying accuracy is improved, but processing complexity increases
Solution Approach 1:
The patent segments the image processing into distinct stages: feature region detection, transmissivity determination, and de-graying processing. By dividing the complex processing into modular steps, the system achieves accurate feature detection while managing computational complexity through structured algorithm design.
