OPERATOR
histogram --- compute greyscale frequency distribution
DESCRIPTION
The histogram operator computes a frequency distribution of the input image.
Either normal or cumulative histograms can be computed. The number of bins
for tallying frequencies is given in the property window along with a low
and high threshold for pixels to be included in the histogram. The result is
a floating point vector of points. The first coordinate of the point is the
bin boundary value and the second coordinate is the bin frequency. The vector
may be viewed by connecting the histogram output to the xgraph operator for
plotting.
