       gpiv_hilo - High-low filtering for PIV images.

SYNOPSIS

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

DESCRIPTION

       gpiv_hilo applies high-low filtering or contrast extension on an image.

       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

       -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.
