A feasibility study of ballet education using measurement and analysis on partial features of still scenes

Abstract

There have been a number of dance and ballet education systems using different multimedia devices. One of the wellknown multimedia devices is Kinect which uses multiple built-in sensors. We focus on Kinect-based dance and ballet education systems. Existing systems that use Kinect cannot properly recognize the turnout movement. We propose the use of a lower body joint point estimation algorithm and a closest foot points estimation algorithm that can efficiently perform image localization for recognition of basic ballet movements. In addition, in order to evaluate correct ballet movements, we propose a method that extracts partial features from still scenes and performs measurements for knee and foot positions. The proposed method is the first ballet education system that properly measures movements of a ballet dancer.

A Feasibility Test on Preventing PRMDs Based on Deep Learning

“…To prevent PRMDs, a variety of methods have been proposed including the analysis of players' posture through wearable and physical sensors. However, the dataset used in these studies (Winges and Furuya 2015), (Park et al 2016) do not consider various situations of the pianist, and are thus biased in posture classification.…”

A Technical Planning for Emotion Evaluation of Art Performance using the Human Emotional Data

“…We will introduce recent popular several kinds of IoT devices as friendly pictures whoever accessible founded in the Google search engine in Figure 1 [9]. [9] Through the IoT Wearable device [5,6,7,8], current emotion of spectators is gathered to the databases in time goes on, then we rapidly extract the exact points of shocking scenes among songs or acting of actors and actresses. This information will give an guidance for objective emotional points of the musical performance whether the spectators be impressed in the which specific scene among all play part or not.…”
