   1. Image
   2. Data points
2. Membership function
   1. Distance functions
   2. Can be manually set or automatically generated from the sample data
   3. Estimators are available to generate membership functions ( ImageModelEstimatorBase, ImageGuassianModelEstimator,ExpectationMaximizationMixtureModelEstimator )
   4. Some classes are named with Estimator suffix but they do more than just estimating membership functions

3. Decison Rules
4. Classifiers
