The video is analyzed to capture the time-varying posture of the dancer's body whereas the musical audio signal is processed to extract the beat information. The human body posture is extracted from multiview video information without any human intervention using a novel marker-based algorithm based on annealing particle filtering. Body movements of the dancer are characterized by a set of recurring semantic motion patterns, i.e., dance figures. Each dance figure is modeled in a supervised manner with a set of HMM (Hidden Markov Model) structures and the associated beat frequency. In synthesis, given an audio signal of a learned musical type, the motion parameters of the corresponding dance figures are synthesized via the trained HMM structures in synchrony with the input audio signal based on the estimated tempo information. Finally, the generated motion parameters are animated along with the musical audio using a graphical animation tool. Experimental results demonstrate the effectiveness of the proposed framework.Electrical electronics engineeringComputer engineeringConference proceedinghttps://www.scopus.com/inward/record.uri?eid=2-s2.0-56449084971anddoi=10.1109%2fSIU.2008.4632725andpartnerID=40andmd5=6fbea9f765311bdac05a192a8d0acf15261359200188N/A8375
