RIVeR v2.5    is out and compiled with MCR 9 - 2015b  What is new ? In the main menu: Embedded PIVlab 2.36 (Release June 2020) Calculates median velocity field instead of mean New sequencing style option added for automatic PIV processing Added pixel size definition if already known in 2D  Control Points definition Added Control Points definition by loading a file (more than 4 points are allowed) Added pixel diagonal size on original image after Control Points definition With 3D rectification, the Control Points are re-projected on the original image (this lets you check quickly if your input is all good) Cross Section vectors are also projected on original image Fixed exporting the current velocity field Fixed minor bugs Updated RIVeR's logo 😎 In the discharge module: Added interpolation of velocity profile with Froude number Added a button that replace velocity at selected station by NaN  Added a check box for NaNs interpolations in velocity profile Added proportion of discharge

RIVeR v2.4.3    is out and compiled with MCR 9 - 2015b (November 2019) What is new ? Added a User Manual (Yeah I know it was time !😉)  Embedded PIVlab 2.3.1 (Release October 4th 2019) Automatic PIVlab (No need to define PIV parameters) in File>PIVlab>PIVlab automatic New colors for the 4 Control Points distances definition adapted for color blindness Added graphic tips for user Added a "flip" button in when loading the stage profile (for profiles that start from right bank) Improved profiles exportation in an Excel file in Export>Current Profiles The mean rectified result is automatically selected after rectification Fixed single image rectification bug Fixed display bugs Fixed minor bugs Enjoy !

RIVeR v2.4.2    is out and compiled with MCR 9 - 2015b (July 2019) What is new ? Resizable windows: Issues were reported for some screen resolutions and the windows were cropped. The windows of RIVeR are now manually resizable. Fixed bug when extracting images from path with spaces. Fixed minor bugs Enjoy !

If you liked RIVeR 2.4  with all its new features you will love RIVeR 2.4.1. with the followings changes: New and more adequate frame extraction method: frame step is now defined instead of frame rate. Fixed the bug when the water level is defined as the same as the first stage point.  Fixed the bug that saved the last unshaked frame into the second unshaked frame. Fixed the bug in the HTML report that displayed the discharge value without applying the coefficient between the mean velocity and the superficial velocity. Fixed the bug that occurred when you defined the CPs with a single length that has more than 3 digits. More bugs fixed...

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>PIVlab Added 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 section Added color code for the extremities of the Cross Sections: red is for the left bank and green is for the right bank Added summary table at the end of the HTML report Fixed minor UI bugs On the Areacomp2 / Discharge menu: Added the mid section method for discharge calculation   Added the % of total discharge curve Fixed minor UI bugs Changes on the Graphic User Interfaces Changes on the generated Html report

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: GRP1 X1 Y1 Z1 x1 y1 GRP2 X2 Y2 Z2 x2 y2 GRP3 X3 Y3 Z3 x3 y3 GRPn Xn Yn Zn xn yn 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: Xi Yi Xj Yj Xk Yk Xi Yi Disclaimer: The video processed in this tutorial is property of USGS and is preliminary or provisional and is subject to revision.
