Abstract: A method for determining lane markers includes providing a camera at a vehicle so as to have a field of view exterior of the vehicle. An image processor processes a frame of image data captured by the camera to determine intensity gradient information of captured image data and to determine lane markers. Contrast values at both sides of a center region of the determined lane marker are determined via processing of the intensity gradient information. An angle of the determined lane marker relative to the direction of travel of the vehicle is determined responsive to the determined contrast values. Processing of a subsequent frame of captured image data is adjusted responsive to the determined angle of the determined lane marker relative to the direction of travel of the vehicle.

Abstract: A vision system of a vehicle includes a camera configured to be disposed at a vehicle so as to have a field of view exterior of the vehicle. An image processor is operable to process image data captured by the camera. The image processor is operable to determine lane markers on a road on which the vehicle is traveling. The image processor processes intensity gradient information of captured image data to determine lane markers, and, responsive to processing of captured image data, the image processor is operable to detect straight or curved lane markers. The image processor is operable to adapt the processing of lane marker image data in subsequent frames of captured image data responsive to image processing of lane marker image data in previous frames of captured image data.

Abstract: There is provided a method for detecting and characterizing abnormalities within biological tissues. The method involves the characterization of the optical properties of the tissue to derive relative values of physiological properties between normal and suspicious regions of the tissue. In some aspects of the invention optical imaging and other imaging modalities are combined to detect and identify a disease state of the tissue.

Abstract: A co-registration system provides a means for spatially warping an optical image of an object with another images of a similar object. The optical image may be a scatter image, and the second image may be the same type of image modality, or may be different. The co-registration may use landmarks selected by a user, or may make use of contour information derived from the images. The system may also include processing of three-dimensional volume data in the form of sets of two-dimensional slices for co-registration.

Abstract: A method for registering a first imaging dataset of a small animal with a second imaging dataset of the animal includes defining a contour of the animal body and dividing it into subregions using skeleton lines. The subregions of the first dataset, once defined, are morphed individually into corresponding subregions of the second dataset. A set of lines may be found for defining each of the subregions, and an index determined which relates the lines of a subregion of the first dataset to those of a corresponding subregion of the second dataset. A pixel index may thereafter be determined for each of the lines, and used to map each pixel of a line to a corresponding list of pixels for the corresponding line of the other dataset.

Abstract: The present invention relates to a method and a system for optical imaging of an object in transmission configuration. The method and system obtain contour coordinates of the object using source/detector configurations references and acquire optical data from a region of interest (ROI) of the object. Then, the method and system apply a weighting factor to said optical data as a function of the contour coordinates, and reconstruct an image of the ROI using the weighted optical data and photon diffusion equation.

Abstract: There is described an infrared (IR) verification system comprising an IR imaging system for capturing thermal signatures, an IR image comparison engine to determine whether a fault exists, a database for thermal failure patterns of printed circuit board assemblies (PCBA) and their proposed diagnosis, and a correlation module to correlate the failure pattern to the database. There is also described a method for using the described system.
