Abandoned object recognition using pedestrian detection
First Claim
1. A method for detecting an abandoned object in one or more images, comprising:
- determining if one or more detected objects in a foreground of said images comprises a potential abandoned object;
applying a trained pedestrian detector to said potential abandoned object to determine if said potential abandoned object comprises at least a portion of a pedestrian, wherein said trained pedestrian detector is trained using positive training samples comprised of at least portions of human bodies in one or more poses; and
classifying said potential abandoned object as an abandoned object based on whether said potential abandoned object is not at least a portion of a pedestrian, wherein at least one of said determining, applying and classifying steps are performed by at least one hardware device.

Abstract
Methods and apparatus are provided for improved abandoned object recognition using pedestrian detection. An abandoned object is detected in one or more images by determining if one or more detected objects in a foreground of the images comprises a potential abandoned object; applying a trained pedestrian detector to the potential abandoned object to determine if the potential abandoned object comprises at least a portion of a pedestrian; and classifying the potential abandoned object as an abandoned object based on whether the potential abandoned object is not at least a portion of a pedestrian. The trained pedestrian detector is trained using positive training samples comprised of at least portions of human bodies in one or more poses and/or negative training samples comprised of at least portions of abandoned objects.

13. An apparatus for detecting an abandoned object in one or more images, said apparatus comprising:
-
a memory; and at least one hardware device, coupled to the memory, operative to; determine if one or more detected objects in a foreground of said images comprises a potential abandoned object; apply a trained pedestrian detector to said potential abandoned object to determine if said potential abandoned object comprises at least a portion of a pedestrian, wherein said trained pedestrian detector is trained using positive training samples comprised of at least portions of human bodies in one or more poses; and classify said potential abandoned object as an abandoned object based on whether said potential abandoned object is not at least a portion of a pedestrian. - View Dependent Claims (14, 15, 16, 17, 18)

19. An article of manufacture for detecting an abandoned object in one or more images, comprising a tangible machine readable recordable storage medium containing one or more programs which when executed implement the step of:
-
determining if one or more detected objects in a foreground of said images comprises a potential abandoned object; applying a trained pedestrian detector to said potential abandoned object to determine if said potential abandoned object comprises at least a portion of a pedestrian, wherein said trained pedestrian detector is trained using positive training samples comprised of at least portions of human bodies in one or more poses; and classifying said potential abandoned object as an abandoned object based on whether said potential abandoned object is not at least a portion of a pedestrian. - View Dependent Claims (20, 21, 22)
