摘要:

尽管最近在基于图像的非真实感渲染(NPR),特别是肖像图像风格化方面的活动激增,但由于神经风格转移的出现,该领域的性能评估的状态是有限的,特别是与计算机视觉和机器学习社区的规范相比。不幸的是,评价图像风格化的任务迄今为止还没有得到很好的定义,因为它涉及主观,感性和美学方面。为了取得进展的解决方案,本文提出了一个新的结构化,三个层次,基准数据集的风格化的肖像图像的评估。严格的标准用于其建设,其一致性是由用户研究验证。此外,已经开发了一种新的方法来评估肖像风格化算法,该方法利用不同的基准水平以及用户研究提供的关于面部特征的注释。我们使用新的基准数据集对各种图像风格化方法(包括肖像专用和通用方法,以及传统的NPR方法和神经风格转移)进行评估。

英文摘要:

Despite the recent upsurge of activity in image-based non-photorealistic rendering (NPR), and in particular portrait image stylisation, due to the advent of neural style transfer, the state of performance evaluation in this field is limited, especially compared to the norms in the computer vision and machine learning communities. Unfortunately, the task of evaluating image stylisation is thus far not well defined, since it involves subjective, perceptual and aesthetic aspects. To make progress towards a solution, this paper proposes a new structured, three level, benchmark dataset for the evaluation of stylised portrait images. Rigorous criteria were used for its construction, and its consistency was validated by user studies. Moreover, a new methodology has been developed for evaluating portrait stylisation algorithms, which makes use of the different benchmark levels as well as annotations provided by user studies regarding the characteristics of the faces. We perform evaluation for a wide variety of image stylisation methods (both portrait-specific and general purpose, and also both traditional NPR approaches and neural style transfer) using the new benchmark dataset.
