M. Renuka Devi, Sarat Saharia · 2016
The single-hand gestures of Indian classical dance are termed as `Asamyukta Hastas' which is a combination of two Sanskrit words, asamyukta meaning `single' and hastas meaning `hand gestures'. This paper introduces a simple two-level classification method for asamyukta hastas of Sattriya dance which is an Indian classical dance form. In the first level, twenty nine classes of hastas are categorized into three groups based on their structural similarity. Then, in the next level hastas are individually recognized from the database within the group. Moreover, the proposed method extracts Medial Axis Transformation (MAT) from the captured images to identify the groups in the first level. One of the applications of the outcome of this research work can be in the e-learning and self learning of the dance hand gestures (mudras or hastas).
