Flow-Based Color Transfer for Vector Graphics Recoloring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current graphics editing software requires extensive manual effort to recolor artwork, often resulting in aesthetically unpleasant outcomes due to the complexity of managing color themes across multiple components in digital visual content.
Innovation Solution
The implementation of flow-based color transfers between source and target graphics, where a palette flow is computed to map colors from a source color palette to a target color palette, allowing for a weighted combination of source colors to modify the target graphic, thereby simplifying the recoloring process and improving aesthetic quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual recoloring is performed to transfer color themes between artworks, then color theme transfer can be achieved, but extensive manual effort and time are required
Solution Approach 1:
The patent replaces manual mechanical color selection and application with an automated image processing system. The system automatically extracts color palettes from source and target images, computes optimal color mappings, and applies recoloring without human intervention, thus eliminating extensive manual effort while maintaining color theme transfer quality
Solution Approach 2:
The system performs self-service by automatically analyzing the source and target images to determine the best color transfer approach. It extracts color palettes, computes transfer functions, and applies recoloring autonomously based on the input images, without requiring user guidance on which colors to map or how to adjust the process
2Ease of manufacture
If manual recoloring is performed to transfer color themes, then color theme transfer can be achieved, but aesthetically unpleasant results may occur requiring rework
Solution Approach 1:
The system incorporates feedback mechanisms by computing color distributions and earth-mover distances to evaluate the quality of color transfers. It uses this feedback to iteratively improve the recoloring process, adjusting color mappings to minimize aesthetic discrepancies and ensure high-quality results that match the intended color theme
Solution Approach 2:
The patent applies parameter changes by adjusting color space transformations and transfer function parameters to optimize the recoloring outcome. It modifies color distribution parameters, saturation levels, and brightness mappings to achieve aesthetically pleasing results while maintaining the integrity of the original artwork's structure
3Quantity of substance
If color palettes are extracted from vector graphics with multiple paths and layers, then comprehensive color information can be captured, but processing complexity increases
Solution Approach 1:
The system segments the color extraction process by separately analyzing different elements of the vector graphic such as paths, layers, and color stops. It processes each segment independently to extract color information, then integrates the results to create a comprehensive color palette, thus managing complexity through systematic division of tasks
Solution Approach 2:
The patent applies preliminary action by pre-processing the vector graphic to identify and organize color information before the main recoloring operation. It extracts and stores color palettes from source and target images in advance, preparing transfer functions and color mappings that can be applied efficiently during the actual recoloring process

AI summary
Certain embodiments involve flow-based color transfers from a source graphic to target graphic. For instance, a palette flow is computed that maps colors of a target color palette to colors of the source color palette (e.g., by minimizing an earth-mover distance with respect to the source and target color palettes). In some embodiments, such color palettes are extracted from vector graphics using path and shape data. To modify the target graphic, the target color from the target graphic is mapped, via the palette flow, to a modified target color using color information of the source color palette. A modification to the target graphic is performed (e.g., responsive to a preview function or recoloring command) by recoloring an object in the target color with the modified target color.
