GPIV_MKTESTIMG(1)					      General Commands Manual						 GPIV_MKTESTIMG(1)

NAME

       gpiv_mktestimg - Generates a simplified image for image processing.

SYNOPSIS

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

DESCRIPTION

       gpiv_mktestimg  generates  an  image  (pair)  in order to be processed by the processing tools. This program is provided for developing and
       testing image processing tools.

       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

       -t N | --threshold N
	      Threshold value

       -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_imgproc - Image processing program for (PIV) images.

SYNOPSIS

       gpiv_imgproc  [-b N] [--filter N] [-h | --help] [-p | --print] [-o N | --operation N] [-t N | --threshold N] [-w N] [-v | --version] [file-
       name] < stdin > stdout

DESCRIPTION

       gpiv_imgproc processes, filters or converts images in order to improve the interrogation  for  Particle	Image  Velocimetry.   gpiv_smooth:
       smoothing  filter,  gpiv_hilo  : high-low filter, gpiv_clip: clipping, gpiv_fft: Fast Fourier Transform, gpiv_invfft: Inverse  Fast Fourier
       Transform, gpiv_highpass: high-pass filtering gpiv_getbit: get bit bumber.  gpiv_mktestimg: generates test image-pair for PIV

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

Options
       -b N   In case of using gpiv_getbit N denotes the bit number [0, .., 7]

       --filter N
	      Image filter to be applied: make test image (N=0), smoothing (N=1), high-low filtering (N=2), clipping (N=3), fft (N=4), inverse fft
	      (N=5), lowpass filter (N=8), highpass filter (N=9), getbit (N=10).

       -h | --help
	      On-line help

       -o N | --operation N
	      In case of using gpiv_smooth: set pixel equal to the mean of the window value (N0), subtract mean from from  pixel  (N1)	add  (N2),
	      multiply (N3) or divide (N4)

       -t N | --threshold N
	      In case of using gpiv_clip: threshold value to be set to zero

       -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.
