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