论文摘要
虚拟音乐家在当代多媒体艺术中已成为一个了不起的现象。但是，如今的大多数虚拟音乐家都没有能力创造自己的行为或与人类音乐家一起表演音乐。在本文中，我们首先创建了一个虚拟小提琴家，他可以与人类钢琴家合作，在没有任何干预的情况下自动执行室内音乐。该系统结合了来自各个领域的技术，包括实时音乐跟踪，姿势估计和身体运动产生。在我们的系统中，仅基于给定的音乐音频就会生成虚拟音乐家的行为，并且这样的系统会产生低成本，高效且可扩展的方式，以产生人类和虚拟音乐家的共同表现。拟议的系统已在公共音乐会中得到了验证。还讨论了客观质量评估方法和系统改进系统的可能方法。
Virtual musicians have become a remarkable phenomenon in the contemporary multimedia arts. However, most of the virtual musicians nowadays have not been endowed with abilities to create their own behaviors, or to perform music with human musicians. In this paper, we firstly create a virtual violinist, who can collaborate with a human pianist to perform chamber music automatically without any intervention. The system incorporates the techniques from various fields, including real-time music tracking, pose estimation, and body movement generation. In our system, the virtual musician's behavior is generated based on the given music audio alone, and such a system results in a low-cost, efficient and scalable way to produce human and virtual musicians' co-performance. The proposed system has been validated in public concerts. Objective quality assessment approaches and possible ways to systematically improve the system are also discussed.
