Biomechanical investigation of tasks concerning manual materials handling using response surface methodology.

In typical manual material handling, the variations in walking pattern are decided by various factors, such as load being handled, frequency of handling, walking surface, etc. Traditional gait analysis protocols commonly evaluate individual factor within specified ranges associated with particular activities or pathologies. However, existing literature underscores the concurrent impact of multiple factors on gait. This study identifies five pivotal factors-walking speed, surface slope, load carried, carrying method, and footwear-as contributors to gait alterations. To address risk factors in m…

GaitSpoofNet: advanced spatio-temporal architectures for vision-based presentation attack detection.

INTRODUCTION: Gait recognition offers a promising non-intrusive biometric modality, but its widespread adoption is critically hindered by its vulnerability to spoofing attacks, also known as Presentation Attacks (PAs). Developing effective gait anti-spoofing, or Presentation Attack Detection (PAD), mechanisms is therefore paramount for the security and reliability of gait-based authentication systems. While anti-spoofing research in gait has been addressed across both sensor-based (accelerometer/gyroscope) and vision-based (silhouette/image) modalities, this work specifically focuses on vision…

A public dataset of treadmill walking kinematics and kinetics at steady speeds in healthy individuals.
