Neural style transfer (NST) has evolved significantly in recent years. Yet, despite its rapid progress and advancement, existing NST methods either struggle to transfer aesthetic information from a style effectively or suffer from high computational costs and inefficiencies in feature disentanglement due to using pre-trained models. This work proposes a lightweight but effective model, AesFA -- Aesthetic Feature-Aware NST. The primary idea is to decompose the image via its frequencies to better disentangle aesthetic styles from the reference image while training the entire model in an end-to-end manner to exclude pre-trained models at inference completely. To improve the network's ability to extract more distinct representations and further enhance the stylization quality, this work introduces a new aesthetic feature: contrastive loss. Extensive experiments and ablations show the approach not only outperforms recent NST methods in terms of stylization quality, but it also achieves faster inference.

该研究提出了一种轻量级但有效的模型，名为AesFA，用于从参考图像中更好地解离美学风格，并通过在整个模型中进行端到端训练来完全排除预训练模型进行推理。为了改进网络提取更明显的表示和进一步增强风格化质量，该研究还引入了一种新的美学特征：对比损失。大量的实验证明，该方法在风格化质量方面不仅优于最近的神经风格转换方法，而且实现了更快的推理速度。
