다국어 초록 (Multilingual Abstract)

Extracting key frame in the animation is crucial for archiving, retrieving, and also for making more optical posture or movement of the character. In this sense, extracting key frames of ballet works is critical to abstract the main points of ballet story and motion information. Ballet is composed of very artistic and scientific movement based on limb actions: extension, flexion, rotation and abduction. Thus, it is meaningful to focus on the ballet specialized method and to develop more appropriate way to inform the ballet movement information. This paper addresses new approaches to find a ballet specialized key frame using ballet key poses and the ballet notation system: Benesh Movement Notation system, and also speculates an effective way to present them in the end. To extract ballet key poses, 168 poses are selected by the Vaganova technique. 168 postures, including basic ballet pose: 5 feet and 3 arm poses are selected and all of these poses are exported to bvh file format by the DanceForms software. These selected 168 poses are then considered as input data to compare ballet key poses in real ballet works(1309 frames). To make a graphic readable platform to change 168 ballet key poses into numerical format, Benech movement notation principles are applied. BMN puts the human body on five staves followed by head, shoulder, waist, knee, and foot levels. Consequently, each pose is expressed as relative joint coordinates in that BMN grid is a mathematical understructure to calculate relative joint position. To extract the main key frames in the whole sequence, the Euclidean Distance was used to calculate the pose similarity distance between original ballet key poses and poses in 1309 frames, and the results were presented as musical score type bye the DanceForms, in the end. Consequently, this paper shows the key pose-based scoring using ballet notation system is efficient to catch the ballet points, in the end.
