• Keywords: Vector Graphics, Style Transfer, Graphic Design, Creative Support Tools, AI and Human Collaboration, Computational Design Tools

Research Background and Problem

• Problems and Challenges:

  • Designers need to improve or unify design styles while preserving the existing design structure, which often involves a significant amount of manual work.
  • Popular design tools (e.g., Adobe Illustrator, Figma) lack flexibility and are not well-suited for style transfer tasks.
  • Fully automated style transfer tools may fail to meet designers' specific needs due to algorithmic limitations and the subjective nature of design styles.

• Research Significance:

  • As an industry standard, vector graphics are widely used in graphic design due to their high editability and scalability. Developing new tools to simplify style transfer can enhance designers' efficiency and creative expression.
  • Automating and enabling interactive handling of style transfer tasks can significantly reduce the repetitive and tedious workload for designers.

• Research Motivation and Related Work:

  • Existing methods (e.g., CSS stylesheets, visual correspondence algorithms) can partially achieve visual style transfer but suffer from significant limitations in flexibility and usability.
  • Previous research on design structure inference, automated transfer techniques, and vector graphic design tools provides a theoretical and practical foundation for tool development.

Solution

• Proposed Solution:

  • Developed a design tool called VST (Vector Style Transfer) that allows designers to interactively and flexibly transfer visual styles between vector graphics.
  • VST provides a dynamic list of element styles, enabling designers to select, reset, and customize various style attributes of elements while supporting style extraction from multiple sources.

• Innovations:

  • Integration of automation and interactive control: Combines automated computation of design element correspondence and style attribute copying with user customization capabilities, allowing designers to edit style transfers at multiple levels.
  • Real-time visual feedback: The output canvas is instantly redrawn with the transferred target design, enabling designers to review results in real time.
  • Extension of traditional copy-and-paste style functionality to grouped elements, making style transfer more efficient.

• Implementation Steps and Underlying Technologies:

  1. Built the user interface using ReactJS and rendered vector graphics with FabricJS.
  2. Employed a multi-image-based automated design correspondence algorithm to generate element mappings between source and target designs.
  3. Enabled designers to adjust the mapping relationships between selected elements via an interactive interface, customizing style transfer modes.
  4. Provided real-time updates to the target design's appearance and supported vector graphic export.

Research Outcomes

• Specific Outcomes:

  • The VST tool enables designers to effectively extract and transfer styles from complex designs.
  • Experiments demonstrate that designers can flexibly complete style transfer tasks across various design scenarios using VST.

• Advantages:

  • Reduces the time and effort required for style transfer compared to traditional industry tools like Adobe Illustrator.
  • Offers robust style customization capabilities, making the tool adaptable to the specific needs of different designers.

• Experimental and Evaluation Results:

  • User studies showed that participants successfully completed tasks and generated satisfactory new designs using VST.
  • Experiments revealed that style transfer using VST typically reduced the time required by approximately 75% compared to manual tools.
  • The quality of the new designs was comparable in visual consistency to manually replicated results by designers.

• Limitations and Future Directions:

  • VST currently focuses on vector graphic design and does not yet support style extraction directly from images.
  • First-time users of VST may require time to adapt to the tool interface, and the existing algorithm needs further optimization for complex design matching.
  • Future research could explore mixed image and vector graphic style transfer and attempt to implement multi-template style unification features in design tools.
