Automated Movement Examination: Skeleton-Based Human Action Recognition for Cognitive Impairment Detection
摘要
Significant attention has recently gone to skeleton-based human action recognition. The goal is to extract features from human skeletons and estimate human poses. However, current methods only capture action information while in real-world applications like cognitive assessment, it is essential to measure executive functioning to help psychiatrists identify mental diseases such as Alzheimer’s, Schizophrenia and Attention-Deficit/Hyperactivity Disorder (ADHD). In this paper, based on the embodied cognition theory, we introduce the Automated Movement Examination (AME) model, a cognitive assessment system using skeleton-based action recognition. AME integrates a pose estimator to extract human body joints, predict the human action and then automatically measures executive functioning. We designed two score functions to measure executive functioning: step score and time score. Our model was evaluated on two different datasets, demonstrating that our approach significantly outperforms existing methods.
