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 130 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.

Abstract: A method, data processing system, apparatus, and computer program product for monitoring objects. A plurality of images of an area is received. An object in the area is identified from the plurality of images. A plurality of points in a region within the area is identified from a first image in the plurality of images. The plurality of points has a fixed relationship with each other and the region. The object in the area is monitored to determine whether the object has entered the region. A determination that the object has not entered the region is made in response to identifying an absence of a number of the plurality of points in a second image in the plurality of images.

Abstract: Objects are monitored using a plurality of received images of an area 600. An object (106, Fig.1) in the area is identified from the images. A plurality of points 508 and (509, Fig.5) in a region 504 within the area is identified from a first one of the images, such that the points have a fixed relationship with each other and the region. The object is monitored to determine whether it has entered the region. If an absence of a number of the points (509, Fig.5) in a second one of the images is identified, it is determined that the object has not entered the region â e.g. a train, rather than the object, has entered the region. The images may be captured by a camera (102, Fig.1) connected to an object monitoring system (202, Fig.2) which is further connected to a train detection system.
