1. A method of registering an object model in an image, the object model comprising a plurality of features, the object model described by a model state, comprising:

  • selecting an unused model feature based initially on a prior state probability model, and subsequently on a propagated state probability model;

    searching for a match of the selected model feature to the image to register the feature;

    updating the state probability model based on the optimal configuration, the updated state probability model being propagated for a next iteration; and

    repeating the steps of selecting, searching and updating.
