NAME

       gpiv_smooth - Image smoothing program for PIV images.

SYNOPSIS

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

DESCRIPTION

       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.

Options

       -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)

       filename
              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.
