       gpiv_smooth - Image smoothing program for PIV images.


       gpiv_smooth  [-h  |  --help] [-p | --print] [-o N | --operation N] [-w N] [-v | --version]
       [filename] < stdin > stdout


       gpiv_smooth set each pixel value  equal  to  the  mean  within  a  window  and  eventually
       subtracts, adds, mulriplies or divides the mean value.

       The parameters read from the configuration resources (containing the key GPIV_IMGPROC) may
       be overruled by the command line options, as explained below.


       -h | --help
              On-line help

       -o N | --operation N
              Set pixel equal to the mean of the window value (N0), subtract mean from from pixel
              (N1) add (N2), multiply (N3) or divide (N4)

       -v | --version
              Print version information on standard output, then exit successfully.

       -w N   window size (default: 15)

              Input  image  filename.  Overrides  stdin  and stdout with the full filename of the
              image.  Output  will  be  written  to  filename.png.  Parameters  are   stored   in
              filename.par and may be used for future use by including them in ./gpivrc. If stdin
              and stdout are used, the input is expected to be a PNG formatted image.
