| Abstract(in English) | We propose a rhythm extraction method utilizing short term principal component analysis (ST-PCA) for motion video in order to automatically evaluate rhythm of a dance. Especially, rhythm features are extracted without explicit background separation by ST-PCA for each segment of entire video sequences, which consists of cyclic motion of basic dances. Furthermore, we enhance the method for online-evaluation of the dance rhythm by comparing the rhythm between a student and a teacher from segment to segment. Our experimental results have shown that our method was effective for online rhythm evaluation with latency less than 2 seconds. The accuracy between visual evaluation and objective one was 0.86, when ST-PCA with analysis windows with twice length of the cycle was applied. |
