Synopsis
WlzHistogramSmooth [-o<output object file>] [-a] [-h]
           [-s<smoothing>] [<input object file>]
Options
-a output the histogram as ascii data not a Woolz histogram object.
-s smoothing factor.

By default the input histogram object is read from the standard input and the output histogram data/object is written to the standard out- put.
The smoothing factor is the gaussian kernel half-height full-width in bins (default 1).
Description
Smooths a Woolz histogram object by convolving the histogram bins with a gaussian.
Output ascii data are written as a set of records one per line, with each record composed of two fields separated by white space characters:
  <grey value>   <histogram bin occupancy>
Examples
