1. A method of processing images captured from an environment, comprising the steps of:

  • detecting features in a set of two or more source images;

    tracking the features to two or more destination images that surround the two or more source images;

    identifying potential correspondences between features from different source images that track to the same image and that satisfy a feature similarity metric; and

    selecting a maximal set of corresponding features from among the potential correspondences to form a set of image feature that is globally consistent across the set of two or more source images.
