Claim 0:
1. A method of identification, comprising:
capturing an image of a scene using an autonomous personal companion providing services to a user, wherein the scene is taken from a physical environment including the user;
identifying at the autonomous personal companion an object in the image of the scene;
determining a contextualization of the physical environment and the user based on a current time period;
filtering a plurality of generic classifiers of a classifier hierarchy independent of the object that is identified based on the contextualization of the physical environment and the user to obtain a group of generic classifiers that is active for the current time period, wherein each of the group of generic classifiers that is active has been searched for purposes of identifying one or more objects for the user;
determining a first plurality of probabilities that the object matches generic classifiers in the group of generic classifiers;
selecting at the autonomous personal companion a first generic classifier from the group of generic classifiers defining broad categories of objects using object data determined for the object obtained from the image, the first generic classifier selected as being representative of the object and having a highest probability of the first plurality of probabilities that meets a threshold probability, the each of the group of generic classifiers defining a corresponding parent node of a corresponding hierarchical tree of classifiers; and
walking a first hierarchical tree of classifiers of the first generic classifier by matching classifiers at one or more levels in the first hierarchical tree of classifiers to the object data until reaching an end classifier at a deepest level to identify an object class for the object, wherein at each level of the first hierarchical tree of classifiers including one or more sub-classifiers for the each level determining a second plurality of probabilities that the object matches the one or more sub-classifiers for the each level and selecting a sub-classifier for the each level having a highest probability of the second plurality of probabilities that meets the threshold probability.
