Research on Construction of a Database for the Traditional Folk Dance and its Applications

我们提出了一个三维数字舞蹈笔记(Buyo-fu)来记录传统的民间舞蹈。通过将运动捕捉(MOCAP)捕获的人体运动数据分割成基元来生成Buyo-fu。在本研究中，我们探讨了以下课题，以求将不育富的实际应用。1)不育富的自动生成：为了自动生成不育富，我们开发了两种方法：一种是利用MOCAP数据波形中包含的特征，另一种是基于自组织映射的方法。2)不育富数据库的构建：我们构建了一个具有易搜索能力的不育富数据库。当检索所需内容时，我们可以使用手势名称或动作名称作为搜索关键字。3)舞蹈作曲家的开发：我们开发了一种舞蹈作曲家，通过将PC.4上的Buyo-fu连接起来来创作舞蹈。我们还讨论了一种在具有无线局域网连接的PDA上显示舞蹈的方法。我们可以通过互联网从数据库中下载舞蹈数据，并在任何地方欣赏舞蹈。5)公众使用的舞蹈数据库的构建：当记录舞蹈时，照片、视频和音乐被记录在一起。由于我们认为不育赋也被用作CG材料，所以希望以几种格式记录不同的不育富。因此，我们开发了一种存档方法，可以使用MPEG7方案综合记录几种格式的数据，供公众使用。我们在两年内完成了步步高实际使用的基础研究。在取得丰硕成果的基础上，我们将为几个传统领域的专家开发一种遗赠技术。

We have proposed a Buyo-fu (3-dimensional digital dance note) to document a traditional folk dance. A Buyo-fu is made by segmenting human movement data captured by a motion capture (MOCAP) into primitives. In this research, we have discussed the following subject in order to make practical use of the Buyo-fu.1) Automatic generation of a Buyo-fu: In order to automatically generate a Buyo-fu, we have developed two methods: one exploits the characteristics included in waveforms of MOCAP data, and the other is based on the self-organizing map.2) Construction of a Buyo-fu database: We have constructed a Buyo-fu database with easy searching capability. When retrieving requested contents, we can use a gesture name or motion name as a search key.3) Development of a dance composer: We have developed a dance composer to create a dance by concatenating Buyo-fu's on a PC.4) Development of a dance viewer: We have developed a dance viewer by which we can appreciate a danced on a PC. We have also discussed a method by which a dance can be displayed on a PDA with wireless LAN connectivity. We can download dance data from a database via the Internet and appreciate a dance anywhere.5) Construction of a dance database for public use: When documenting a dance, photographs, videos and music are recorded together. Since we consider that the Buyo-fu is also exploited as CG materials, it is desired to record a Buyo-fu in several formats. Hence, we have developed an archiving method that can comprehensively record the data in several formats using a MPEG-7 scheme for public use.We have completed fundamental research on making practical use of the Buyo-fu in two years. Based on the fruitful results, we will develop a bequeathing technique for the skill of experts in several traditional fields.
