摘要： A method for re-identifying an image is provided. The method comprises obtaining a plurality of images and generating a correspondence map between the plurality of images. The method further comprises defining a plurality of region signatures for one or more regions comprising the plurality of images and comparing the plurality of images based on the correspondence map and the plurality of region signatures to perform image re-identification.

摘要： The present invention aims at providing a method for detecting a color of a signal light from a moving vehicle such as railroad train. The method includes capturing an image from a camera mounted on the moving vehicle and extracting candidate regions in the image that contain light region. The method further includes classifying the candidate regions as a signal light region or a non-signal light region and identifying the color of the signal light region.

摘要： A device and method for processing an image to create appearance and shape labeled images of a person or object captured within the image. The appearance and shape labeled images are unique properties of the person or object and can be used to re-identify the person or object in subsequent images. The appearance labeled image is an aggregate of pre-stored appearance labels that are assigned to image segments of the image based on calculated appearance attributes of each image segment. The shape labeled image is an aggregate of pre-stored shape labels that are assigned to image segments of the image based on calculated shape attributes of each image segment. An identifying descriptor of the person or object can be computed based on both the appearance labeled image and the shape labeled image. The descriptor can be compared with other descriptors of later captured images to re-identify a person or object.

摘要： A device and method for efficient computation of statistical information, such as a mean, co-variance, or histogram of the image pixels, over discrete image regions. The computation employs integral computations to determine the statistical information over image regions of arbitrary shape, including irregular polygonal shaped regions. The integral computations are simplified by categorizing corner points of boundaries of image regions. The computation can be applied to calculate descriptors or signatures of persons or objects within an image. The computation also has a low computational cost enabling fast calculation of image statistics.

摘要： A camera calibration system providing a first transmitter capable of transmitting a first signal; a second transmitter capable of transmitting a second signal; a second receiver and a third transmitter capable of transmitting a first plurality of signals. The second receiver and the third transmitter being movable together as a common unit so that the second receiver receives the first signal and the second signal and so that the first plurality of signals are receivable by a first camera to be calibrated. The system provides for a processor in electrical communication with the second receiver and the first camera, the is processor capable of receiving a second plurality of signals from the first camera to be calibrated, the second plurality of signals indicative of receipt of said first plurality of signals. Further, the processor is capable of generating a third signal indicative of calibration of the first camera and being configured to determine a relative coordinate system of the common unit, the first transmitter and the second transmitter, and the first camera based at least in part on the first signal, the second signal, and the second plurality of signals.
