Automatic generation of Labanotation based on human pose estimation in folk dance videos
Neural Computing and Applications(2023)
Abstract
Existing Labanotation generation methods have some drawbacks due to low efficiency and incapability to recognize existing videos, which can also be affected by the quality of hardware equipment. To address the issues in existing methods, we propose a new Labanotation generation method for folk dance videos based on pose estimation. Specifically, our method first extracts the key frame images from the fork dance video using temporal differences. Afterward, the 2D joint points of a dancer can be detected from key frame images by using multi-scale fusion of high-resolution net (HRNet), then maps the 2D–3D joint point sequence of the dancer using a pose projection generative adversarial network (pose projection GAN) to predict the coordinates of the 3D joint point position. Finally, the corresponding Labanotation can be generated by analyzing the estimate posture. Experimental results show that the method can achieve the conversion of dance movements in folk dance videos into digital Labanotation, and the automatic generation is much more efficient than manual recording. This method can quickly record endangered folk dances and contribute to the preservation and transmission of movement-based intangible cultural heritage.
