The combination of face identification and action recognition for fall detection

Introduction

Falls are a very common unexpected accident in the elderly that results in serious injuries such as broken bones, and head injury. Detecting falls and taking fall patients to the emergency room on time is very important. In this project, we propose a method combining face and action recognition for fall detection. Specifically, we identify seven basic actions in elderly daily life based on skeleton data detected using the YOLOv7-Pose model. Two deep models, Spatial-Temporal Graph Convolutional Network (ST-GCN) and Long Short-Term Memory (LSTM), are employed for action recognition on the skeleton data. The experimental results on our dataset show that the ST-GCN model achieved an accuracy of 90% higher than the LSTM model by 7%.
