Overview
For each Interrogation Area of an image, gpiv_aint calculates the mean image intensity. Depending on the settings of the interrogation scheme, the Interrogation Area's may be shifted with magnitude of the piv estimators (if they exist) or the image may be deformed before the intensity is calculated.
This program uses the IMG, PIV and POST parameters. The default settings may be overruled by the command line options, as explained below.
Options
-
-h | --help -
On-line help.
-
-p | --print -
Prints parameters to stdout.
-
-s | --second -
Calculates the image intensitites for the second image frame in case of double-frame image pairs.
-
-V | --verbose -
Prints data of interrogation area's and resulting mean.
-
-v | --version -
Print version information on standard output, then exit successfully.
- filename
-
Full name of the image file. Image format might be: png, raw binary (.r), hdf5 (.hdf), gif, tif, bmp or pgm. The piv estimators are read from filename
.pivThe settings are written to filename.par. output will be stored in filename.ain.
