Statistical analysis of three‐dimensional optical flow separability in volumetric images

IET Computer Vision, 2015
Three‐dimensional (3D) motion analysis of dynamic body organs using volumetric images is of increasing interest in different computer vision applications. A number of methods for estimation of 3D optical flow in those images have been developed in recent

Front Crawl Is More Efficient and Has Smaller Active Drag Than Backstroke Swimming: Kinematic and Kinetic Comparison Between the Two Techniques at the Same Swimming Speeds

Frontiers in Bioengineering and Biotechnology, 2020
The purpose of this study was to investigate differences in Froude efficiency (ηF) and active drag (DA) between front crawl and backstroke at the same speed. ηF was investigated by the three-dimensional (3D) motion analysis using 10 male swimmers.

Deformable and articulated 3D reconstruction from monocular video sequences [PDF]

, 2012
PhDThis thesis addresses the problem of deformable and articulated structure from motion from monocular uncalibrated video sequences. Structure from motion is defined as the problem of recovering information about the 3D structure of scenes imaged by a

Volumetric motion quantification by 3D tissue phase mapped CMR

Journal of Cardiovascular Magnetic Resonance, 2012
Background The objective of this study was the quantification of myocardial motion from 3D tissue phase mapped (TPM) CMR. Recent work on myocardial motion quantification by TPM has been focussed on multi-slice 2D acquisitions thus excluding motion ...

Concurrent validity of a developed accelerometry-based device for postural sway assessment [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2020
Postural control is one factor related to falls. Many instruments are available to objectively evaluate postural control performance. However, feasibility and applicability is limited by setting and financial restraints.

Estimation of 3D Head Region using Gait Motion for Surveillance Video [PDF]

, 2011
Detecting and recognizing people is important in surveillance. Many detection approaches use local information, such as pattern and colour, which can lead to constraints on application such as changes in illumination, low resolution, and camera view ...
