WlzHistogramEqualiseObj

Name

WlzHistogramEqualiseObj - Histogram equalises a Woolz domain object.

Synopsis

WlzHistogramEqualiseObj [-o<output object file>] [-h]
           [-D] [-s<smoothing>] [<input object file>]

Options

-D	dither pixel value when mapping
-s	histogram smoothing factor.
-o	Output object file name.
-h	Help - print help message
-v	Verbose operation

By default the input object is read from the standard input and the output object is written to the standard output.

Description

Histogram equalises the given Woolz domain object so that the histogram of the modified object's grey values approximates a uniform histogram.

The smoothing factor is the low-pass gaussian convolution kernel half-height full-width in bins (default 0), used to smooth the objects histogram before equalisation.
