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.
Indicate the colorspace.
Set to MagickTrue to print detailed information about the identified classes.
This represents the minimum number of pixels contained in a hexahedra before it can be considered valid (expressed as a percentage).
the smoothing threshold eliminates noise in the second derivative of the histogram. As the value is increased, you can expect a smoother second derivative.
