DrawFromDrawings: 2D Drawing Assistance via Stroke Interpolation with a Sketch Database
DrawFromDrawings assists 2D drawing with visual feedback from a sketch database. This system offers novel stroke suggestions and deformations, enhancing artistic creation and speeding up composition.
Area of Science:
- Computer Graphics
- Human-Computer Interaction
- Digital Art
Background:
- Traditional art education relies on imitation and emulation.
- Digital drawing tools often lack intuitive guidance for complex stroke creation.
- Interactive systems can bridge the gap between user input and desired artistic output.
Purpose of the Study:
- To introduce DrawFromDrawings, an interactive system for 2D drawing assistance.
- To enable users to leverage a database of sketch images for feedback.
- To explore novel stroke generation and feedback mechanisms in digital art creation.
Main Methods:
- Utilizing a database of sketch images for user reference.
- Detecting as-long-as-possible (ALAP) stroke segments and correspondences between user and reference sketches.
- Implementing stroke-level interpolation by parameterizing user, reference, and warped reference strokes based on region of interest (ROI) shapes.
- Offering two feedback modes: suggestive (overlay) and deformation (replacement).
Main Results:
- User studies confirmed that stroke interpolation can generate diverse strokes with varying shapes and complexity.
- Suggestive feedback facilitated idea development while preserving the user's stroke style.
- Deformation feedback accelerated the completion of sketch compositions.
Conclusions:
- DrawFromDrawings provides effective visual feedback for 2D drawing assistance.
- The system's interpolation and feedback mechanisms support both creative exploration and efficient sketching.
- Interactive drawing systems can significantly enhance the digital art creation process.
