WebPIVlab is an easy to use Matlab toolbox that calculates velocities in image data (movies, pictures). It uses a method called 'Particle Image Velocimetry'. Usually, this method is used to calculate velocities in fluids. But there are also many other possibilities. Recently, ensemble correlation was added, making PIVLab suitable for micro-PIV too. WebMicro-particle image velocimetry (μPIV) is a quantitative method that can be used to characterize the performance of such microfluidic systems with spatial resolutions better than one micron. Illustrating the impact of this measurement technique, more than 100 journal articles are published per year that feature μPIV velocity measurements. ...
