I wish you all the best for 2019 !
How to better start this new year with a new version of RIVeR ?!
Thanks to your feedback RIVeR 2.4 is now available  and here are the changes:

On the main menu:
Embedded PIVlab 2.00 :  The wonderful tool developed by William Thielicke is finally available directly from RIVeR from File>PIVlabAdded Cross-section panel. It is now possible to edit the coordinate of an existing Cross-Section (in pixel and real world coordinates).Added edit of number of samples over the cross sectionAdded color code for the extremities of the Cross Sections: red is for the left bank and green is for the right bankAdded summary table at the end of the HTML reportFixed minor UI bugs On the Areacomp2 / Discharge menu:
Added the mid section method for discharge calculation  Added the % of total discharge curveFixed minor UI bugs

Tutorial for 3D rectification

Image
As you know RIVeR lets you rectify results with Control Points that are in the same plane but also when you have a 3D cloud of points. And here you can whatch a video of the propper workflow.



The  GRP.xls file is a 6 columns files with the following structure:

GRP1X1Y1Z1x1y1GRP2X2Y2Z2x2y2GRP3X3Y3Z3x3y3GRPnXnYnZnxnyn With (X,Y,Z) the real world coordinates and (x,y) the pixel coordinates


The Real World Roi.xls file must have a 2 colums structure:

Do you find difficulties to process shaky videos from your UAV or maybe you didn't have any tripod while you were recording or simply you want to analyze an interesting phone video you found in some social network #citizenscience ???
In the new version of RIVeR you can now stabilize your media and this is how you can do it:
Enjoy ;-)


1. Extract the frames from the video
2. In RIVeR Files->Unshake images select all the images you want to stabilize
3. Draw a mask in order to cover the water surface
4. Select Unshake

See the video example below:

You can now also play around with  RIVeR-STIV that will allow you to do Space Time Image Velocimetry. The STIV analysis (and specially the texture orientation) is based on the work presented in Fujita et al., (2007) Fujita, I., Watanabe, H., Tsubaki, R., 2007. Development of a non-intrusive and efficient flow monitoring technique: The space‐time image velocimetry (STIV). Int. J. River …
If you ever use RIVeR for your researches, you can now reference it ! DOI: 10.1016/j.cageo.2017.07.009
Thanks to all of you for your feedback and helping to make RIVeR a better tool ! ;-)
