Visual Text Generation with Separate Content and Style Adapters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional diffusion models struggle with generating coherent and realistic images when modifying text style based on a style reference image, often producing incoherent results due to limited text editing capabilities and incompatibilities between background and text.
Innovation Solution
An image generation apparatus using a diffusion model with separate text content and style adapters, along with a background adapter, to provide content and style guidance information, ensuring accurate depiction of text with seamless integration into the image background.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional diffusion models are used for text style transfer, then the model structure remains simple, but the text coherence and style accuracy deteriorate
Solution Approach 1:
The model is segmented into distinct components: a text encoder for content understanding, a style encoder for style extraction, and a diffusion model for image generation. This segmentation allows each component to specialize in specific tasks, improving text style accuracy while maintaining manageable complexity through modular architecture
Solution Approach 2:
Two encoder modules are introduced as intermediaries between the input text and the diffusion model. These encoders transform text into content embeddings and style embeddings, which then guide the diffusion process. This intermediary approach enables precise control over text coherence and style accuracy without requiring the diffusion model itself to be overly complex
2Reliability
If text editing capabilities are enhanced, then text coherence improves, but compatibility between background and text deteriorates
Solution Approach 1:
The model applies different quality requirements to different aspects of text generation: high coherence is enforced through the text encoder that captures semantic meaning, while adaptability to background is achieved through the style encoder that extracts visual style features. This local quality approach allows simultaneous optimization of both text coherence and background-text compatibility
Solution Approach 2:
The model changes parameters by introducing separate content and style embeddings that can be independently adjusted. The content embedding controls text coherence while the style embedding controls adaptability to background. This parameter separation allows the system to maintain high text coherence while simultaneously achieving good background-text compatibility
3Manufacturing precision
If style guidance is added to diffusion models, then style accuracy improves, but the generation process complexity increases
Solution Approach 1:
Style guidance is prepared in advance through the style encoder, which extracts style embeddings from reference images before the diffusion generation process begins. This preliminary action allows the style information to be pre-processed and organized, improving style accuracy while reducing the complexity burden during the actual generation process
Solution Approach 2:
The style encoder acts as an intermediary that transforms complex style information from reference images into compact style embeddings. These embeddings then serve as simplified guidance signals for the diffusion model, achieving high style accuracy while keeping the generation process manageable through this intermediate representation

AI summary
A method, apparatus, non-transitory computer readable medium, and system for image generation include obtaining a text content image and a text style image. The text content image is encoded to obtain content guidance information and the text style image is encoded to obtain style guidance information. Then a synthesized image is generated based on the content guidance information and the style guidance information. The synthesized image includes text from the text content image having a text style from the text style image.
