Research on Recognition Method of Non-Legacy Dance Action Based on Multi-Feature Fusion

Intangible Cultural Heritage (ICH) dances, with their richness in historical and cultural value, reflect the diversity of human society. However, many traditional dances face challenges with their transmission and protection. This paper proposes a multi-feature fusion-based motion recognition method to address insufficient feature extraction and inadequate model adaptability for ICH dance movement recognition. The method integrates skeletal, spatiotemporal, and deep features, enhancing their expression through an optimised fusion strategy and using an improved 3D convolutional neural network for efficient recognition. Validation on a dataset of 60 typical movements from various ICH dances including Dai peacock dance, Tibetan Guozhuang dance, Mongolian Andai dance, and Uyghur sainaim dance demonstrated superior performance of this method in accuracy, recall, and F1 score compared to traditional methods. This research provides a robust solution for ICH dance movement recognition and offers insights towards broader technological applications for cultural preservation.
