First Claim
1. A method comprising:
- accessing a training set including a target object set and a clutter object set, the target object set including a target associated with a target feature value and the clutter object set including a non-target object associated with a clutter feature value;
determining that the training set includes multiple types of targets or multiple types of clutter;
comparing the target feature value of a type of target with the clutter feature value;
associating the type of target with the non-target object based on the comparison;
training a classifier using the target feature value and the clutter feature value of the associated type of target and the non-clutter object such that the classifier produces a metric that indicates that an object associated with the type of target is a target;
generating multiple classifiers, the multiple classifiers including the trained classifier;
applying a feature value associated with an unknown object to the multiple classifiers to generate a set of metrics for the unknown object;
aggregating the metrics into an overall metric; and
determining whether the unknown object is included in the target set based on the overall metric.

Abstract
A training set including a target object set and a clutter object set is accessed. It is determined that the training set includes multiple types of targets or multiple types of clutter. The target feature value of a type of target is compared with the clutter feature value. The type of target is associated with the non-target object based on the comparison. A classifier is trained using the target feature value and the clutter feature value of the associated type of target and the non-clutter object. A feature value associated with an unknown object is applied to multiple classifiers to generate a set of metrics for the unknown object. The metrics are aggregated into an overall metric. Whether the unknown object is included in the target set is determined based on the overall metric.
