Patent ID: 7734071

Claim:
A method for determining a component, the component to be used by a component-based object identification system, the method comprising: using a processor to determine an accuracy of a first component recognition classifier, wherein the first component recognition classifier determines to which class a given component belongs and was trained based on a first component, the first component representing a first object region; determining a set of enlarged components, an enlarged component being larger than the first component, the enlarged component representing a second object region, wherein the second object region is larger than the first object region and contains the first object region; for each enlarged component in the set of enlarged components, determining an accuracy of a second component recognition classifier, wherein the second component recognition classifier determines to which class a particular component belongs and was trained based on the enlarged component; determining, from among the first component recognition classifier and each second component recognition classifier, which component recognition classifier is most accurate; and determining which component was used to train the most accurate component recognition classifier.
