ABSTRACT Semantic segmentation is an important approach to present the perceptual semantic understanding of an image, which is of significant usage in various applications. Especially, body part segmentation is designed for segmenting body parts of human characters to assist different editing tasks, such as style editing, pose transfer, and animation production. Since segmentation requires pixel‐level precision in semantic labeling, classic heuristics‐based methods generally have unstable performance. With the deployment of deep learning, a great step has been taken in segmenting body parts of human characters in natural photographs. However, the existing models are purely trained on natural photographs and generally obtain incorrect segmentation results when applied on anime character images, due to the large visual gap between training data and testing data. In this article, we present a novel approach to achieving body part segmentation of cartoon characters via a pose‐based graph‐cut formulation. We demonstrate the use of the acquired body part segmentation map in various image editing tasks, including conditional generation, style manipulation, pose transfer, and video‐to‐anime.

Computer Animation and Virtual Worlds

随着功能强大的个人电脑和高端显卡的出现，虚拟世界、实时计算机动画和模拟、游戏出现了令人难以置信的发展。但与此同时，出现了新的、更便宜的虚拟现实设备，允许与这些实时虚拟世界甚至通过增强现实与现实世界进行交互。 3D 角色，尤其是虚拟人现在具有卓越的品质，可以在电影行业中使用它们。但这只是一个开始，随着人工智能和智能体技术的发展，这些角色将变得越来越自主甚至智能。他们将与动物和植物一起在虚拟生活中居住在虚拟世界中。

With the rapid advancement of personal computers and high-end graphics cards, significant progress has been made in the fields of virtual worlds, real-time computer animation, simulation, and gaming. At the same time, the emergence of new and more affordable virtual reality devices allows for interaction with these real-time virtual worlds, even integrating augmented reality with the real world. 3D characters, especially virtual humans, now possess exceptional quality and can be utilized in the film industry. However, this is just the beginning. As artificial intelligence and agent technologies continue to evolve, these characters will become increasingly autonomous and even intelligent. They will coexist with animals and plants in virtual life within these virtual worlds.
