Walking gait dataset

Introduction

The dataset has been established to enable comparative studies on gait analysis, especially the problems of gait index estimation and abnormal gait detection. The dataset includes 9 gaits that are normal (symmetric) walking gait and 8 simulated abnormal (asymmetric) ones. Since the dataset contains 3 synchronized data types (point cloud, skeleton, frontal silhouette), this is appropriate for assessment on many gait-related methods. This page briefly describes the dataset and provides the download links.

Data description

The dataset was acquired by the system containing:

Acquired walking gaits: There were 9 volunteers in our dataset, in which each subject performed 9 walking gaits with different levels of symmetry. Each walking gait was acquired in 1200 consecutive frames.
