Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple input modalities are integrated into the image synthesis system, then user flexibility and control over image generation are enhanced, but device complexity increases
Solution Approach 1:
The system segments the complex image synthesis task into multiple independent input modalities (text input, sketch input, segmentation map input, and reference image input), each processed by dedicated encoder networks. This segmentation allows users to selectively combine modalities for desired control levels while maintaining modular system architecture that manages complexity through functional decomposition.
Solution Approach 2:
The image synthesis system is designed with multi-functionality to accept and process multiple types of inputs (text, sketches, segmentation maps, reference images) through a unified GAN framework. This universal interface enables the same system to serve diverse user needs ranging from fully automatic text-to-image generation to controlled editing with multiple input types, thereby enhancing adaptability without requiring separate systems for each function.
2Manufacturing precision
If multiple input modalities are combined for image synthesis, then the precision and diversity of output images improve, but the complexity of input processing increases
Solution Approach 1:
The input processing is segmented into specialized encoder networks for each modality type (text encoder, sketch encoder, segmentation map encoder, reference image encoder). Each encoder is optimized for its specific input type, enabling precise processing of complex inputs while maintaining modular architecture that simplifies the overall processing complexity through functional specialization.
Solution Approach 2:
The system introduces an intermediary conditioning mechanism that aggregates information from multiple input modalities and translates them into a unified condition vector that guides the GAN generation process. This intermediary layer harmonizes the diverse input formats and complexities, enabling precise control over image generation without directly exposing the complexity of multi-modal processing to the core synthesis mechanism.
