1. A computer implemented method for determining a probability distribution of a classification of labels for nodes of a first image by comparing the first image to a second image, the computer implemented method comprising:

  • a. defining a set of labels for each node in a plurality of nodes on the first image wherein a label of the set of labels indicates a corresponding node on the second image, a classification of a current node on the first image, and a classification of the corresponding node on the second image;

    b. calculating local descriptive information for multiple mappings between, and multiple classification assignments of, the plurality of nodes of the first image and corresponding nodes on the second image;

    c. inputting at least some of the descriptive information into a probabilistic model, wherein the probabilistic model accounts for classification assignments of the current node combined with different variants of corresponding nodes on the second image;

    d. determining one or more probabilities of classification for at least some of the nodes; and

    e. providing the determined probabilities of classification.
