Abstract: The invention is a method for estimating a product of convolution of a measurement function, representing measurements, defined according to first coordinates, with a convolution kernel. The convolution product is estimated at second coordinates, different from said first coordinates. The measurement function represents measurements performed on the basis of a detector, in particular a detector of physical quantities. An exemplary application of the method relates to Magnetic Resonance Imaging, the method allowing a redistributing of measured data, not uniformly distributed, according to a uniform mesh, prior to the application of a fast Fourier transform algorithm.

Abstract: A system and method for determining positional order of vehicles across a threshold plane within a dynamic environment is provided. The system can include moving vehicles (e.g., boats) each having a GPS receiver. A reference object (e.g., an anchored boat) can have an image capturing device and a primary GPS receiver, and can be subject to movement induced by the dynamic environment. A fixed object having a known position (e.g., a government buoy) relative to the reference object define a threshold plane, which is subject to movement based on movement of the reference object. Photometric data gathered by the image capturing device and geospatial data gathered from the GPS receivers, the primary GPS receiver, and the fixed object is analyzed by a processor to determine a positional order at which each vehicle crossed the movable threshold plane.

Abstract: Segmentation is the process of partitioning an image into regions under certain rules. One implementation is to separate human objects that appear in a sequence of images (video) from the background. The goal is to find humans and segment them out in real-time, fully automatic (with no user input), and the result is produced immediately after a new image is captured. Once the segmentation process is started, the method is constantly learning (or updating) the decision rule for segmenting out human objects from the background by itself. Moving object detection by a Kalman filter-based approach roughly detects the region where moving objects are present.

Abstract: Distribution information of examination results of eye fundus is displayed. An imaging part carries out movie imaging of fundus. A tomographic image forming part comprises an optical system that generates and detects interference light by superposing signal light from fundus on reference light and a scanner that scans fundus with signal light, and forms tomographic image of fundus based on detection results of interference light acquired by the scanning. A setting part sets scan-target location of signal light on distribution information. A specifying part specifies image region in fundus image obtained by the movie imaging that corresponds to the scan-target location. A controller controls the scanner based on the specified image region to carry out scanning of signal light. The tomographic image forming part forms tomographic image from the detection results of interference light acquired by the scanning of signal light based on the control.

Abstract: A method and an apparatus for recognizing characters using an image are provided. A camera is activated according to a character recognition request and a preview mode is set for displaying an image photographed through the camera in real time. An auto focus of the camera is controlled and an image having a predetermined level of clarity is obtained for character recognition from the images obtained in the preview mode. The image for character recognition is character-recognition-processed so as to extract recognition result data. A final recognition character row is drawn that excludes non-character data from the recognition result data. A first word is combined including at least one character of the final recognition character row and a predetermined maximum number of characters. A dictionary database that stores dictionary information on various languages using the first word is searched, so as to provide the user with the corresponding word.

The technology is particularly well-suited for use in comparing geometric changes of aneurysms, tumors, thromboses, inflammations.
