Patent Number Title Of Patent Date Issued
6532311 Image browser March 11, 2003
In an image browser for browsing a deck of hyperspectral images, the images of the deck are divided into square blocks each containing 25 pixels. The images are browsed by selecting foci of attention in selected images in sequence. Each time a focus of attention is selected, the image bl
6516097 Image segmentation system February 4, 2003
In a system for segmenting a pixel based image, pixels containing image boundaries are identified. The image boundaries are then fattened by repeatedly adding fattening rows of pixels to the pixels containing boundaries to separate the remaining pixels into separate segments. The sep
6150973 Automatic correction of phase unwrapping errors November 21, 2000
In a phase unwrapping and correction system, phase wrapped data is unwrapped with an unwrapping algorithm to obtain unwrapped image data. The unwrapped image data is further processed to correct the unwrapped image data by dividing the image represented by the unwrapped image data into
5926581 System for topographic mapping from remotely sensed images July 20, 1999
In a method for generating a model of terrain, images of the terrain are generated at different angles. Matching points in the images are identified and from these matching points, the coefficients of a registration mapping equation are determined. A height term of the registration m
5689717 Method and apparatus for the placement of annotations on a display without overlap November 18, 1997
A method and system for placing annotations of various sizes on a display without overlapping the annotations is described. Each annotation is represented by its rectangular bounding box along with an identifying line or arrow that joins the rectangle with the display object that is to b
5680138 Synthetic aperture radar simulation October 21, 1997
In a simulated synthetic aperture radar SAR, a terrain elevation model is provided. A phase component of the simulated SAR data is computed by determining a distance between incremental terrain points and a simulated SAR platform modulo the wavelength. The amplitude component is computed
5608405 Method of generating visual representation of terrain height from SAR data employing multigrid a March 4, 1997
In a method of recovering data representing terrain height from a synthetic aperture radar system the phase data is unwrapped by a Gauss-Seidel relaxation technique applied to a least squares differential equation in a multigrid algorithm. In the multigrid algorithm the problem represent
