NAME
       gpiv_aint - Calculates mean image intensity at each interrogation area.

SYNOPSIS
       gpiv_aint [-h | --help] [-p | --print] [-s | --second] [-V | --verbose] [-v | --version] filename

DESCRIPTION
       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.piv The settings are written to filename.par. output will be stored in filename.ain.

NOTES
       The program uses netpbm.
