High Recognition Accuracy Achieved in SVM-Based Action Recognition Model

Researchers from Chengdu Sport University in China have developed an SVM-based action recognition model that utilizes skeletal key point analysis with posture sensors to provide accurate sports training analysis tools. The study, published in Bmc Sports Science Medicine and Rehabilitation, employed the quaternion method to model human skeleton features, acquired motion data through a posture sensor, and performed preliminary data processing using the Kalman filtering technique. The model achieved a high recognition accuracy of 91.24% for both static and dynamic actions.

Key Takeaways:

  • The study proposes an SVM-based action recognition model that integrates human action recognition in sports training, aiming to provide an accurate sports training analysis tool.
