GPIV_IMGPROC(1) General Commands Manual GPIV_IMGPROC(1)NAMEgpiv_imgproc - Image processing program for (PIV) images.SYNOPSISgpiv_imgproc [-b N] [--filter N] [-h | --help] [-p | --print] [-o N | --operation N] [-t N | --threshold N] [-w N] [-v | --version] [file- name] < stdin > stdoutDESCRIPTIONgpiv_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.
