ICA를 통한 우리 춤의 감정인식

초록

Recently, endeavors for recognizing human emotion from full body movements. Especially, dance which is close to common human motions that are the most typical of expressing human emotion, have been made. Korean dance includes Korean peculiar emotion, which discriminates Korean dance from Western dance. Therefore, the unique method for analyzing and recognizing emotion from Korean dance has been strongly required. To the best of our knowledge, there is no method for recognizing emotion from korean dance in the literature. In this thesis, we propose a method for recognizing emotion from Korean dance and analyzing Korean dance using the recognition results. The method consists of four steps. First, dance performances associated with pre-defined emotions are extracted from several representative Korean dances based on professional dancers' qualitative analysis and danced by professional dancers. Second, the dance performances are captured using multiple cameras and quantitative features associated with dance performances are extracted from the camera images using a series of image processing algorithms. Furthermore, the features are analysed by ICA(independent Coponent Analysis) more useful than PCA(Principle Component Analysis).Third, the mapping between the dance performances and the pre-defined emotions is estimated using neural network. Finally, given arbitrary dance performances, their corresponding emotions are recognized using the neural network. Thus, the purpose of this thesis is extracting sequential emotional patterns of Korean dance using the emotion recognition method. and proposing a criterion for specifying the characteristics of Korean dance quantitatively. The quantitative analysis can concrete the results of the existing researches on understanding the characteristics of Korean dance depend only on the qualitative analysis. We expect that this thesis provides a systematic framework for understanding the characteristics of the whole Korean dance through the qualitative and quantitative analysis of some representative Korean dances.
