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. Param-
	      eters  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.

NAME

       gpiv_vhisto - Tests PIV data by printing/displaying an histogram of the vertical particle displacements.

SYNOPSIS

       gpiv_vhisto [-g] [-h | --help] [-n N] [-p | --print] [-v | --version] [filename] < stdin > stdout

DESCRIPTION

       Gpiv_vhisto calculates the histogram of the vertical particle displacement distribution between minimum and maximum values.

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

Options
       -g     Graphical visualization of the histogram with gnuplot.

       -h | --help
	      On-line help

       -n N   Override number of bins (default 10, hard coded).

       -p | --print
	      Print parameters, command line options and eventually used input and output filenames to stdout.	The output  is	identic  of  file-
	      name.par, in case -f is used.

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

       filename
	      Input  PIV  file.  Overrides stdin and stdout. Output will be written to filename.pdf. The parameters will be written or appended to
	      filename.par and may be used for future use by including them in ./gpivrc.

NOTES

       stdin and stdout has still to be implemented.  [-f filename ] will be added.

BUGS

       The program seems to work fine with real PIV data.  So far, no serious bugs have been found.
