Video of new (faster, more robust) auto-calibration for camera based water level measurement

The following is a video of our new auto-calibration capability.  Previously it took a big effort to calibrate the GaugeCam water measurement software because it was necessary to specify a region of interest for each of the calibration target ficucials.  In addition, the previous algorithm struggled with degraded images.  This video demonstrates the new ease of use and calibration robustness even with bad images.
