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

212<p>the image.</p>
213
214<h5>colorspace</h5>
215<p>Indicate the colorspace.</p>
216
217<h5>verbose</h5>
218<p>Set to MagickTrue to print detailed information about the identified classes.</p>
219
220<h5>cluster_threshold</h5>
221<p>This represents the minimum number of pixels contained in a hexahedra before it can be considered valid (expressed as a percentage).</p>
222
223<h5>smooth_threshold</h5>
224<p>the smoothing threshold eliminates noise in the second derivative of the histogram. As the value is increased, you can expect a smoother second derivative.</p>
