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 ...
