[Insight-users] some questions of using itk::KalmanLinearEstimator to fit linear function !

[Luis Ibanez]

Hi Zhen,

The ITK class that implements the Kalman Linear Estimator is:

http://www.itk.org/Insight/Doxygen/html/classitk_1_1KalmanLinearEstimator.html


An example of its use is available at

     Insight/Testing/Code/Algorithms/
               itkKalmanLinearEstimatorTest.cxx


This example actually does exactly what you are asking for:


      "Fit a 6D linear equation to a set of points"



You *MUST* read the introductory paper to Kalman estimation

   http://www.cs.unc.edu/~welch/media/pdf/kalman_intro.pdf

that is available along with many other useful documents at
the following UNC web site:


         <http://www.cs.unc.edu/~welch/kalman/>



   Regards,



      Luis
