Claim 17:
18. The computer system of claim 15, wherein the walking the first hierarchical tree of classifiers of the first generic classifier includes:
walking the first hierarchical tree of classifiers until reaching the end classifier at the deepest level to identify the object class, the first hierarchical tree of classifiers including one or more hierarchical levels of classifiers under a parent node such that succeeding lower levels include more specific classifiers trained using more specific training data, each classifier in the first hierarchical tree of classifiers comprising a corresponding set of weights based on corresponding training data, wherein the walking the first hierarchical tree of classifiers until reaching the end classifier at the deepest level includes,
beginning with a next highest level directly below the first generic classifier as the parent node, determining at least one probability generated by executing one or more classifiers of the next highest level using the object data;
matching the object data to a matched classifier of the next highest level generating the highest probability;
determining if an adjacent lower level is connected to the matched classifier;

labeling the adjacent lower level as the next highest level; and
recursively performing until there is no adjacent lower level, wherein a last occurring matched classifier is the end classifier.
