Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conditional generative adversarial networks with spatially-adaptive normalization are used to generate synthesized digital images, then image quality during semantic image generation is improved, but the resulting quality is still inferior to unconditional generative adversarial networks and resolution is limited
Solution Approach 1:
The system segments the image generation process by dividing objects into different classes (e.g., foreground objects, background objects) and applying different generator networks to each class. This allows specialized optimization for each object type while maintaining overall system organization, resolving the contradiction between quality and complexity through structured division of labor.
Solution Approach 2:
The system applies local quality by using class-specific generator networks that are tailored to generate particular types of objects with appropriate levels of detail. Each generator network is optimized for its specific object class, providing locally optimized quality rather than a uniform approach, which improves overall image generation quality without requiring excessive global complexity.
2Measurement precision
If existing image generation systems generate synthesized digital images, then images are produced, but the resolution sizes are limited and not useful for real-world applications
Solution Approach 1:
The system performs preliminary action by pre-training separate generator networks for different object classes before final image generation. This pre-training phase allows each generator to specialize in specific object types at high resolution, enabling the final synthesis to achieve high resolution without sacrificing generation efficiency during the actual image production phase.
3Manufacturing precision
If a single generator network is used to generate all objects in synthesized digital images, then the generation process is simpler, but the accuracy and detail representation of individual objects is reduced
Solution Approach 1:
The system applies segmentation by dividing the object generation task into multiple specialized generator networks, each responsible for specific object classes. This segmentation enables each network to focus on learning the unique characteristics and details of its assigned object class, achieving high object detail accuracy while maintaining manageable complexity through organized specialization.
Solution Approach 2:
The system achieves universality by designing a framework where multiple specialized generator networks work together within a unified architecture. Each generator is specialized for a particular object class, but collectively they provide universal coverage for generating diverse image content, balancing specialization benefits with system-wide coordination.
