Image smoothing program for piv images.
gpiv_smooth [-h | --help] [-p | --print] [-o N | --operation N] [-w N] [-v | --version] [filename] < stdin > stdout
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.
-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. 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.
