20090003511 | Device and Method For Identifying Occlusions - A method of identifying one or more occlusions in vasculature located in a region of interest, includes extracting vasculature from the region of interest; identifying a subject geometry of the extracted vasculature; and comparing the subject geometry to a predetermined geometry to identify a blockage. A device for identifying one or more occlusions in vasculature located in a region of interest is also presented. | 01-01-2009 |
20090012382 | METHOD AND SYSTEM FOR DETECTION OF OBSTRUCTIONS IN VASCULATURE - A method for automatic detection of obstructions in vasculature in an anatomical region is presented. The method includes partitioning the anatomical region into a plurality of sub-regions based at least in part on anatomical knowledge. Further, the method includes adaptively computing a threshold intensity value corresponding to each of the plurality of sub-regions. Additionally, the method includes extracting the vasculature in each of the plurality of sub-regions based on the corresponding computed threshold intensity value, where the extracted vasculature comprises a plurality of vessel segments. The method also includes detecting an obstruction in the extracted vasculature. Systems and computer-readable medium that afford functionality of the type defined by this method is also contemplated in conjunction with the present technique. | 01-08-2009 |
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 |
20100135453 | Multi-material decomposition using dual energy computed tomography - A method for obtaining multi-material decomposition images is disclosed, the method comprising the steps of: acquiring an image pair from a dual energy computed tomography scan of an imaged object; selecting a material basis for multi-material decomposition of the image pair; applying a physicochemical model for the material basis; and performing multi-material decomposition using at least one constraint imposed by the physicochemical model. | 06-03-2010 |
20120308100 | METHOD AND SYSTEM FOR RECONSTRUCTION OF TOMOGRAPHIC IMAGES - Approaches are described for generating an initial reconstruction of CT data acquired using a wide-cone system. In one implementation, frequency data may be patched in to a first scan, such as an axial scan, from a second scan, such as a helical scan. In one embodiment, an initial reconstruction may be processed (such as via a non-linear operation) to correct frequency omissions and/or errors in the reconstruction. Corrected frequency information may be utilized to improve the reconstructed image. | 12-06-2012 |
20130148875 | METHODS AND SYSTEMS FOR PROCESSING IMAGES FOR INSPECTION OF AN OBJECT - Methods and systems for processing images are provided. One method includes obtaining a plurality of images corresponding to at least one area of an object and performing a rectification of at least some of the plurality of images using a reference structure. The method also includes performing a gradient vector field analysis on the rectified plurality of images of the object to identify anomaly regions within the object. | 06-13-2013 |
20130188042 | SYSTEM AND METHOD FOR OBJECT MEASUREMENT - A technique is provided for measuring an object based on multiple views. The technique includes registering each of the plurality of images and a first model of the object with one another and reconstructing a second model of the object based on the plurality of images and the first model registered with one another. | 07-25-2013 |
