HOW TO PROCESS A VIDEO USING THE RIVeR 2.2 LSPIV SOFTWARE
See also: http://riverdischarge.blogspot.com/p/tutorial.html

Setup

Since RIVeR is a compiled freeware made in the Matlab environment you should: 

  1. Download and install the Matlab Runtime version #R2015a (64-bit)
  2. Download the latest version of RIVeR

  3. RIVeR uses results from image velocimetry software like PIVlab and PTVlab. For this example, we will only use PIVLab. Both programs are open-source software available on the Matworks file exchange platform as source code. You must have a Matlab license in order to use them otherwise you can always contact me for a compiled version.


In most videos of rivers, one can get good results with 3 passes, 256, 128, 64. I think this works because in most cases, the scale of rivers and height above them we take video is pretty similar.
