Calibration Of Video Object Classification
US Patent:
2013025, Sep 26, 2013
Filed:
May 20, 2013
Appl. No.:
13/897579
Inventors:
Longbin Chen - Sunnyvale CA, US
Rogerio Schmidt Feris - White Plains NY, US
Arun Hampapur - Norwalk CT, US

Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
G06K 9/62
US Classification:
382224
Abstract:
Techniques for calibrating a classification system, wherein one or more objects in at least one video are classified, are provided. At least one view associated with the at least one video is obtained. The at least one view is partitioned into at least one region. A given object is classified in accordance with its location in reference to the at least one region. In an additional embodiment, one or more object models are obtained. At least one normalized size of the one or more objects is defined within at least one view associated with the at least one video in accordance with the one or more object models. The one or more objects are classified in accordance with the at least one defined normalized size.

Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
G06K 9/62
G06K 9/00
G06K 9/00
US Classification:
382224
Abstract:
A system comprises an input component, a feature extractor, an object classifier, an adaptation component and a calibration tool. The input component is configured to receive one or more images, and the feature extractor is configured to extract features for one or more objects in the one or more images, the extracted features comprising at least one view-independent feature. The object classifier is configured to classify the one or more objects based at least in part on the extracted features and one or more object classification parameters, and the adaptation component is configured to adjust the classification of at least one of the objects based on one or more contextual parameters. The calibration tool is configured to adjust one or more of the object classification parameters based on likelihoods for characteristics associated with one or more object classes.
