Class SurfaceRater

java.lang.Object
  edu.jhu.ece.iacl.algorithms.manual_label.simulation.SurfaceRater

public class SurfaceRater
extends java.lang.Object

Simulates a random surface rater characterized by their 1) Probability of error 2) Probability of boundary error (vs global error) 3) Confusion Matrix (for global error) 4) Probability that boundary errors will occur on particular boundaries 5) Probability that the boundary will "shrink" or "grow". Note: A boundary between label i and j (i!=j, i
