Detailed Description

ConvergenceCriteria represents an abstract base class for different convergence criteria used in registration loops.

This should be used as part of an Iterative Closest Point (ICP)-like method, to verify if the algorithm has reached convergence.

Typical convergence criteria that could inherit from this include:

  • a maximum number of iterations has been reached
  • the transformation (R, t) cannot be further updated (the difference between current and previous is smaller than a threshold)
  • the Mean Squared Error (MSE) between the current set of correspondences and the previous one is smaller than some threshold
