摘要:

作为图像增强的重要子课题,颜色迁移旨在在保留语义内容的前提下,依据参考图像增强源图像的配色方案。为实现颜色迁移,学界已提出基于调色板的颜色映射框架,这是一种无需依赖复杂语义分析即可生成新配色方案的经典方案,但该框架通常需要手动设置,实用性有所降低。传统调色板生成的质量取决于颜色分离的程度。本文提出一种新型基于调色板的颜色迁移方法,可自动生成新的配色方案。通过重新设计的基于调色板的聚类方法,像素可根据颜色分布被划分为不同片段,适用性更强。结合基于深度学习的图像分割与新型颜色映射策略,可分别对前景和背景部分执行颜色迁移,同时保持语义一致性。实验结果表明,该方法在自然真实感、颜色一致性、通用性和鲁棒性方面,相较同类方法具有显著优势。

英文摘要:

As an important subtopic of image enhancement, color transfer aims to enhance the color scheme of a source image according to a reference one while preserving the semantic context. To implement color transfer, the palette-based color mapping framework was proposed. \textcolor{black}{It is a classical solution that does not depend on complex semantic analysis to generate a new color scheme. However, the framework usually requires manual settings, blackucing its practicality.} The quality of traditional palette generation depends on the degree of color separation. In this paper, we propose a new palette-based color transfer method that can automatically generate a new color scheme. With a redesigned palette-based clustering method, pixels can be classified into different segments according to color distribution with better applicability. {By combining deep learning-based image segmentation and a new color mapping strategy, color transfer can be implemented on foreground and background parts independently while maintaining semantic consistency.} The experimental results indicate that our method exhibits significant advantages over peer methods in terms of natural realism, color consistency, generality, and robustness.
