## SegmentImage

SegmentImage() segment an image by analyzing the histograms of the color components and identifying units that are homogeneous with the fuzzy C-means technique.

The format of the SegmentImage method is:

    MagickBooleanType SegmentImage(Image *image,
      const ColorspaceType colorspace,const MagickBooleanType verbose,
      const double cluster_threshold,const double smooth_threshold)

A description of each parameter follows.

image

the image.

colorspace

Indicate the colorspace.

verbose

Set to MagickTrue to print detailed information about the identified classes.

cluster_threshold

This represents the minimum number of pixels contained in a hexahedra before it can be considered valid (expressed as a percentage).

smooth_threshold

the smoothing threshold eliminates noise in the second derivative of the histogram. As the value is increased, you can expect a smoother second derivative.
