Feature Expression Of Digital Dancing Art And Technique Of Video Retrieval

With the development of society,dancing art has more and more influence on our life and economy day by day. It is the best form of different forms of record medium for dancing. Digitalization is a kind of current trends,and its advantage is obvious. So,the digitalization of the dancing video becomes inevitable. With accumulation of digital dancing videos,how to store,manage and retrieve them is being one realistic problem.The purpose of our research on feature expression of digitilized dancing and technique of video retrieval is to promote interchange and development of dancing art,Protect and manage dancing video resource,advance development of local dancing artistic resource,etc. We can utilize the technology to set up system as appreciating tool,learning tool,dancing director's tool,etc. We analyse features of digitilized dancing video,propose mothed of feature expression of frames in digital video,Put forward motheds of video parsing,shots partition,key frame obtaining and video retrieval towards digital dancing video. And set up the prototype system of a digital dancing video database.The content of this text is built up as follows:In chapter one,we have analysed the current situation and demand of the dancing and video database,and have explained the research background of the subject.In chapter two,we have analysed and realized the key technology in this research. Aiming at characteristic of dancing video,we have analysed the feature expression of pictures,shot partition,keyframe obtaining and the method of video retrieval.In chapter three,we have analysed video from point of view of operate.and solved compression,partition and joins,playback control of video,etc.In chapter four,we have analysed the design and coding of prototype system of digital dancing video database and the whole structure of system,the designs of the database and interface.In chapter five,we have analysed the existing problem and research direction in the future,and give some examples in several applicable fields of this research.
