Synopsis

WlzHistogramGauss [-h] [-a] [-r] [-o<out file>] [-d#] [-s#] [<in object>]

Options

-h	Help, prints usage message.
-r	Use a recursive IIR filter.
-o	Output object/data file name.
-d	Derivative, range [0-2].
-s	Gaussian sigma (standard deviation).

Examples

WlzHistogramGauss -s3 -a myhist.wlz | xgraph
