Abstract: A geospatial modeling system may include at least one geospatial information database to store stereo-geographic image data and geographic feature data. A processor may cooperate with the geospatial information database for generating cost coefficients defining a three-dimensional (3D) cost cube using image matching operators based upon the stereo-geographic image data, adjusting the cost coefficients of the 3D cost cube based upon the geographic feature data to generate an adjusted 3D cost cube, and generating a geospatial model based upon solving the adjusted 3D cost cube, e.g. for a best cost surface. The system and method provide an integrated approach to creating a geospatial model using available data from multiple sources.

Abstract: A medical image analysis system is for first and second anatomical image data of a same body area and subject to deformation. The first and second anatomical image data includes respective first and second sets of voxels. The medical image analysis system includes a processor cooperating with a memory to generate a respective reach array for each voxel of the second anatomical image data, with each reach array being a subset of contiguous voxels. The processor also generates a cost array for each reach array, with each cost array based upon probabilities of voxels of the reach array matching voxels of the first anatomical image data. The processor may also solve each cost array using belief propagation to thereby generate a deformation vector array between the first and second anatomical image data.

Abstract: A medical image analysis system is for first and second anatomical image data of a same body area and subject to deformation. The medical image analysis system may include a processor cooperating with a memory to generate a deformation vector array between the first and second anatomical image data. The processor may also display, on a display, first and second anatomical images respectively based upon the first and second anatomical image data. A first cursor may be displayed on the first anatomical image, and a second cursor may be displayed on the second anatomical image based upon a mapping of the first cursor using the deformation vector array.

Abstract: A medical image analysis system is for first and second anatomical image data of a same body area and subject to deformation, with the first and second anatomical image data including respective first and second sets of voxels. The medical image analysis system may include a processor cooperating with a memory and configured to generate a plurality of cost arrays, with each cost array based upon probabilities of a subset of voxels of the second anatomical image data matching voxels of the first anatomical image data. The processor may also solve each cost array using three-dimensional, N-way belief propagation to thereby generate a deformation vector array between the first and second anatomical image data, where N is an integer greater than or equal to six.

Abstract: A computer-implemented method for generating an image-textured digital surface model (DSM) for a geographical area of interest including both buildings and terrain may include using a computer to generate a digital elevation model (DEM) of both the buildings and terrain for the geographical area of interest. The method may further include providing a collection of optical images including oblique optical images for the geographical area of interest including both buildings and terrain. The computer may also be used to selectively superimpose oblique optical images from the collection of optical images onto the DEM of both the buildings and terrain for the geographical area of interest and to thereby generate the image-textured DSM for the geographical area of interest including both buildings and terrain.

Abstract: A method for converting between source coordinates in a source coordinate system and target coordinates in a target coordinate system includes the step of defining a coordinate system conversion tree extending from a root coordinate system and branching to a plurality of other coordinate-systems including the source and target coordinate systems so that the source and target coordinate systems are connected to a common coordinate system other than the root coordinate system. Coordinate conversions are performed between the source and target coordinates along branches extending from the source coordinate system to the common coordinate system and to the target coordinate system without returning to the root coordinate system. Contextual data is associated with the coordinates to permit conversion to an adjacent coordinate system.

Abstract: A digital image processing system reduces errors in the parameters of a sensor geometry model, through which points in a captured digital image are geolocated to the surface of the earth by means of a `real time` co-registration mechanism that refines the geometry model associated with the working image in a matter of seconds. Using a co-registration mechanism such as that described in the U.S. Pat. No. 5,550,937, the system co-registers the reduced accuracy working digital image with a reference image, geographical spatial locations of respective pixels of which have been previously determined with a high degree of accuracy. The imagery co-registration operator adjusts the respective geometry models associated with its input images, in accordance with differences in cross-correlations of the respectively different spatial resolution versions of the two images, so as to bring the respective images into effective co-registration on image registration surface.

Abstract: A system and method for storing image data in a location remote from a display device which uses the data. The system uses plural reduced resolution image data sets and geographical coordination between the image being viewed and the data sets to substantially reduce the bandwidth required to transmit the image data and to shorten the time needed for transmission. Automatic transmission of data needed may be utilized.

Abstract: First and second digital images, such as terrestrial images captured by one or more spaceborne or airborne sensors, are transformed onto a registration surface in accordance with geometry models of the sensors, to bring the digital images into mutual alignment on the registration surface. The images are initially subsampled to obtain reduced spatial resolution versions of each image. For a base resolution version of each image, respective neighborhoods of pixels associated with matching point grids in each image are defined. Edge-preemphasized contents of respective neighborhoods of pixels of each image are cross-correlated with one another, to derive a measure of misregistration between the images. One or both of the geometry models of the sensors are modified in accordance with the measure of misregistration, so as to effectively decrease misregistration between the images on the registration surface.

Abstract: A screen-to-registration surface interface translates coordinate system parameters associated with screen-base image manipulation software to latitude and longitude parameters of a co-registration surface-based coordinate system. By invoking a data file linking mechanism of the `windows`-based display and manipulation software, the user may specify a given image manipulation operation to be executed with respect to plural images that have been imported into respective windows of the display. The registration surface coordinate system parameters are compatible with image collection geometry models. These values are then transformed by the respective collection geometry models to the respective digital image files of the linked images.
