Automated method and apparatus for robust image object recognition and/or classification using multiple temporal views
First Claim
1. An automated method for classifying an object in a sequence of video frames, the method comprising:
- tracking the object in multiple frames of the sequence of video frames;
determining feature descriptors for the object for each of the multiple frames;
computing multiple classification scores by matching said feature descriptors for the object for each of the multiple frames with feature descriptors for a candidate class in a classification database; and
aggregating said multiple classification scores to generate an estimated probability that the object is a member of the candidate class.

Abstract
An automated method for classifying an object in a sequence of video frames. The object is tracked in multiple frames of the sequence of video frame, and feature descriptors are determined for the object for each of the multiple frames. Multiple classification scores are computed by matching said feature descriptors for the object for each of the multiple frames with feature descriptors for a candidate class in a classification database. Said multiple classification scores are aggregated to generate an estimated probability that the object is a member of the candidate class. Other embodiments, aspects and features are also disclosed.
