KY 4D Gait Database A (Straight)

Introduction

Kyushu University 4D Gait Database A (Straight) is composed of sequential 3D models and image sequences of people walking along straight trajectories. This database comprises 42 subjects with four sequences for each subject. All people walked along straight trajectories, as indicated by dashed line 1 in the figure. Multiple 3D models were reconstructed by the visual hull technique with 16 cameras placed in the studio. This dataset was first introduced in the EST 2010 paper, Person identification from spatio-temporal 3D gait" [1]. Detailed analysis is available in the paper in Pattern Recognition Letters 2014 Identification of people walking along curved trajectories" [2].


Example sequential 3D models of a person walking straight

Dataset

The KY 4D Gait Database A consists of sequential 3D models of forty two walking people, color and silhouette images taken by 16 cameras, and camera parameters of each camera. For more details, please refer to [1].

Download

You can download dataset from anonymous FTP server (ftp://robotics-ftp.ait.kyushu-u.ac.jp). All images and 3D models are in "gait" folder.
