Object recognition for security screening and long range video surveillance

摘要

A method of detecting an object in image data that is deemed to be a threat includes annotating sections of at least one training image to indicate whether each section is a component of the object, encoding a pattern grammar describing the object using a plurality of first order logic based predicate rules, training distinct component detectors to each identify a corresponding one of the components based on the annotated training images, processing image data with the component detectors to identify at least one of the components, and executing the rules to detect the object based on the identified components.

1. A method of detecting a weapon in image data, the method comprising:
annotating sections of a plurality of training images to indicate whether each section is one of a plurality of different constituent parts of a weapon; encoding a pattern grammar describing the weapon using a plurality of first order logic based predicate rules; training a plurality of distinct component detectors, where each detector is trained to each identify a corresponding one of the weapon parts based on the annotated training images; processing image data with the component detectors to identify at least one of the weapon parts; and executing the rules to detect the weapon based on the identified weapon parts.
