| 20090034791 | Image processing for person and object Re-identification - 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. | 02-05-2009 |

| 20100027009 | METHOD AND SYSTEM FOR DETECTING SIGNAL COLOR FROM A MOVING VIDEO PLATFORM - 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. | 02-04-2010 |
| 20100104513 | METHOD AND SYSTEM FOR DYE ASSESSMENT - The present disclosure generally relates to systems and methods for identifying the boundaries of tumors and assessing quantitatively the ability of dyes to highlight a tumor's boundary. In accordance with these methods and systems, images are taken of subjects administered agents labeled with dyes. After accessing the images, tumors are selected and routines employed to both identify the boundaries of the tumors, as well as, to quantify various aspects of the tumor boundaries. From these quantifiable descriptors the performances of the various dyes to highlight the boundaries of tumors are evaluated. | 04-29-2010 |

| 20110051999 | Device and method for detecting targets in images based on user-defined classifiers - A device and method for detecting targets of interest in an image, such as people or objects of a certain type. Targets are detected based on an optimized strong classifier descriptor that can be based on a combination of weak classifier descriptors. The weak classifier descriptors can include a user-defined weak classifier descriptor that is defined by a user to represent a shape or appearance attribute that is characteristic of parts of the target of interest. The strong classifier descriptor can be optimized by selecting a subset of weak classifier descriptors that exhibit improved performance in detecting targets in training images. | 03-03-2011 |

| 20110075914 | SYSTEM AND METHOD FOR THE QUANTITATIVE ASSESSMENT OF DIGITAL HISTOLOGY IMAGES - The present disclosure concerns a method and system for assessing image quality of sub-images used to form a composite image using an algorithm developed by applying statistical correlation techniques to historical data on features of sub-images which were manually evaluated by experts and using those assessment to make decisions about the further processing of the sub-images which are being assessed. The method and system find particular value in the processing of sub-images generated while there is relative motion between the specimen under examination and the objective lens of a microscope such as when the microscope stage follows a planned traverse in the focal plane and a digital image is created at intervals correlated to the motion of the stage so that a region of interest in the specimen under examination is covered by the sub-images. The further processing decisions include manually examining the sub-images assessed to have unacceptable image quality, reimaging the entire region of interest and recreating specific sub-images. The method and system may also involve overlaying portions of a composite image with an indication that they were drawn from sub-images of unacceptable image quality. | 03-31-2011 |
