摘要:

为了传达目标风格的艺术表现力,近期研究利用注意力机制,因为它能够将风格图像的局部块映射到内容图像的对应块。然而,由于任意内容与艺术作品之间的语义对应性较低,注意力模块会反复滥用风格图像中的特定局部块,导致不和谐且明显的重复伪影。为了克服这一局限并实现完美的艺术风格迁移,我们专注于增强注意力机制并捕捉组织风格的模式的节奏。在本文中,我们引入了一种新的度量,即模式重复性,用于量化风格图像中模式的重复程度。基于模式重复性,我们提出了美学模式感知的风格迁移网络(AesPA-Net),该网络能够发现局部与全局风格表达的最佳平衡点。此外,我们提出了一种新的自监督任务,以促使注意力机制学习精确且有意义的语义对应。最后,我们引入了逐块风格损失,以迁移局部模式的精细节奏。通过定性和定量评估,我们验证了所提出的模式重复性与人类感知一致的可靠性,并证明了所提出框架的优越性。

英文摘要:

To deliver the artistic expression of the target style, recent studies exploit the attention mechanism owing to its ability to map the local patches of the style image to the corresponding patches of the content image. However, because of the low semantic correspondence between arbitrary content and artworks, the attention module repeatedly abuses specific local patches from the style image, resulting in disharmonious and evident repetitive artifacts. To overcome this limitation and accomplish impeccable artistic style transfer, we focus on enhancing the attention mechanism and capturing the rhythm of patterns that organize the style. In this paper, we introduce a novel metric, namely pattern repeatability, that quantifies the repetition of patterns in the style image. Based on the pattern repeatability, we propose Aesthetic Pattern-Aware style transfer Networks (AesPA-Net) that discover the sweet spot of local and global style expressions. In addition, we propose a novel self-supervisory task to encourage the attention mechanism to learn precise and meaningful semantic correspondence. Lastly, we introduce the patch-wise style loss to transfer the elaborate rhythm of local patterns. Through qualitative and quantitative evaluations, we verify the reliability of the proposed pattern repeatability that aligns with human perception, and demonstrate the superiority of the proposed framework.
