Assessing the validity of two-dimensional video analysis for measuring lower limb joint angles during fencing lunge

Frontiers in Sports and Active Living
IntroductionThe fencing lunge (lunge), characterized by minimal body rotation, offers a movement well-suited for 2D video analysis. However, to the best of our knowledge, the validity of 2D video analysis for fencing has not been verified.

Zoom in to the details of human-centric videos

, 2020
Presenting high-resolution (HR) human appearance is always critical for the human-centric videos. However, current imagery equipment can hardly capture HR details all the time.

Vision-Based Mouth Motion Analysis in Epilepsy: A 3D Perspective [PDF]

2019 41st Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2019
Epilepsy monitoring involves the study of videos to assess clinical signs (semiology) to assist with the diagnosis of seizures. Recent advances in the application of vision-based approaches to epilepsy analysis have demonstrated significant potential to automate this assessment. Nevertheless, current proposed computer vision based techniques are unable

A 3D view of the outflow in the Orion Molecular Cloud 1 (OMC-1)

, 2012
The fast outflow emerging from a region associated with massive star formation in the Orion Molecular Cloud 1 (OMC-1), located behind the Orion Nebula, appears to have been set in motion by an explosive event.

A study on sensor position for thigh and lower leg motion sensors during walking (Focusing on the knee sagittal plane angle)

Nihon Kikai Gakkai ronbunshu, 2018
This paper describes the use of nine-axis motion sensors to evaluate the motion sensor position on the thigh and lower leg during walking. The motion sensors are mounted on a subject's body using adhesive tape.

High-Lundquist Number Scaling in Three-Dimensional Simulations of Parker's Model of Coronal Heating

, 2012
Parker's model is one of the most discussed mechanisms for coronal heating and has generated much debate. We have recently obtained new scaling results in a two-dimensional (2D) version of this problem suggesting that the heating rate becomes independent

Computer-Assisted Reconstruction and Motion Analysis of the Three-Dimensional Cell

The Scientific World Journal, 2003
Even though several microscopic techniques provide three-dimensional (3D) information on fixed and living cells, the perception persists that cells are two-dimensional (2D). Cells are, in fact, 3D and their behavior, including the extension of pseudopods,

Validation of a 3D Markerless Motion Capture Tool Using Multiple Pose and Depth Estimations for Quantitative Gait Analysis

Sensors
Gait analysis is essential for evaluating walking patterns and identifying functional limitations. Traditional marker-based motion capture tools are costly, time-consuming, and require skilled operators.
