Particle Image Velocimetry Images

This child item contains the image frames extracted from videos for each field site. The images serve as the input to the Particle Image Velocimetry (PIV) analysis. There are zip archive files for each field site included in this child item. Each of the zip files contain three directories of images: <br> <ul> <li><strong>original:</strong> these are the image frames extracted from the videos without other modification.</li> <li><strong>stable:</strong> these image frames have been created by running the original frames through an image stabilization program. See the FGDC metadata Process Steps for more information.</li> <li><strong>stable_subtracted:</strong> these image frames have been created by using background subtraction on the stabilized images. See the FGDC metadata Process Steps for more information.</li> </ul> <br> In addition to the images zip archives, there is also a comma-separated values file (CSV) summarizing the frame extraction information used to create the original images. <br> Each Field Site is abbreviated in various files in this data release. File and folder names are used to quickly identify which site a particular file or dataset represents. The following abbreviations are used: <ul> <li>ACR: Androscoggin River, Auburn, Maine, USA</li> <li>AFR: Agua Fria River, near Rock Springs, Arizona, USA</li> <li>CCC: Coachella Canal above All-American Canal Diversion, California, USA</li> <li>CMC: Cochiti East Side Main Channel, near Cochiti, New Mexico, USA</li> <li>GLR: Gila River near Dome, Arizona, USA</li> <li>RMC: Reservation Main Canal near Yuma, Arizona, USA</li> <li>SMC: Sile Main Canal (at head) at Cochiti, New Mexico, USA</li> <li>WMD: Wellton-Mohawk Main Outlet Drain near Yuma, Arizona, USA</li> </ul>
