风格中的抽象：超越纹理与色彩
Abstraction in Style: Beyond Texture and Color
AI总结：
提出Abstraction in Style (AiS)框架，将结构抽象与视觉风格分离，通过中间抽象代理实现几何保真度放松，从而支持更广泛的非真实感风格迁移。
摘要：
艺术风格通常嵌入超越表面外观的抽象，涉及对结构的有意重新诠释，而不仅仅是纹理或色彩的变化。传统的风格迁移方法通常保留输入几何结构，因此难以捕捉这种更深层次的抽象行为，尤其是对于插画和非真实感风格。在这项工作中，我们引入了Abstraction in Style (AiS)，一个将结构抽象与视觉风格化分离的生成框架。给定目标图像和少量风格样本，AiS首先推导出一个中间抽象代理，该代理根据风格所展现的抽象逻辑重新诠释目标的结构。代理捕捉语义结构，同时放松几何保真度，使得后续的风格化能够在抽象表示而非原始图像上进行操作。在第二阶段，渲染抽象代理以产生最终风格化输出，保持与参考风格的视觉一致性。两个阶段都使用共享的图像空间类比实现，使得变换可以从视觉样本中学习，无需显式的几何监督。通过将抽象与外观解耦，并将抽象视为显式、可迁移的过程，AiS支持更广泛的风格变换，提高了可控性，并实现了更具表现力的风格化。
英文摘要：
Artistic styles often embed abstraction beyond surface appearance, involving deliberate reinterpretation of structure rather than mere changes in texture or color. Conventional style transfer methods typically preserve the input geometry and therefore struggle to capture this deeper abstraction behavior, especially for illustrative and nonphotorealistic styles. In this work, we introduce Abstraction in Style (AiS), a generative framework that separates structural abstraction from visual stylization. Given a target image and a small set of style exemplars, AiS first derives an intermediate abstraction proxy that reinterprets the target's structure in accordance with the abstraction logic exhibited by the style. The proxy captures semantic structure while relaxing geometric fidelity, enabling subsequent stylization to operate on an abstracted representation rather than the original image. In a second stage, the abstraction proxy is rendered to produce the final stylized output, preserving visual coherence with the reference style. Both stages are implemented using a shared image space analogy, enabling transformations to be learned from visual exemplars without explicit geometric supervision. By decoupling abstraction from appearance and treating abstraction as an explicit, transferable process, AiS supports a wider range of stylistic transformations, improves controllability, and enables more expressive stylization.
