Particle Image Velocimetry Algorithm Based on Spike Camera Adaptive Integration [PDF]
In particle image velocimetry (PIV), overexposure is particularly common in regions with high illumination. In particular, strong scattering or background reflection at the liquid–gas interface will make the overexposure phenomenon more obvious ...

Considerations When Applying Large-Scale PIV and PTV for Determining River Flow Velocity
Large-scale image velocimetry is a novel approach for non-contact remote sensing of flow in rivers. Research within this topic has largely focussed on developing specific aspects of the image velocimetry work-flow, or alternatively, testing specific ...

Grid turbulence studied by Particle Image Velocimetry [PDF]
We studied the grid-generated turbulence by using Particle Image Velocimetry (PIV) technique. We test on this already well studied flow the new ways of analyzing spatially resolved PIV data, such as the spatial spectra and structure functions. We compare
