摘要： A graphics system comprises pixel calculation units and a sample buffer which stores a two-dimensional field of samples. Each pixel calculation unit selects positions in the two-dimensional field at which pixel values (e.g. red, green, blue) are computed. The pixel computation positions are selected to compensate for image distortions introduced by a display device and/or display surface. Non-uniformities in a viewer's perceived intensity distribution from a display surface (e.g. hot spots, overlap brightness) are corrected by appropriately scaling pixel values prior to transmission to display devices. Two or more sets of pixel calculation units driving two or more display devices adjust their respective pixel computation centers to align the edges of two or more displayed images. Physical barriers prevent light spillage at the interface between any two of the display images. Separate pixel computation positions may be used for distinct colors to compensate for color distortions.

摘要： Methods of modifying source images and image streams are described. These methods may be used, for example, to remove embedded digital data from images or to prevent splicing modified portions of the images to recreate the source image. One method includes the receiving a request for a selected portion of a source image stream comprising a plurality of source image frames. A distorted grid is applied to the selected portion to generate a modified selected portion. The grid is distorted spatially, temporally, or both. The modified selected portion of the source image stream in response to the request. The distortion is designed to introduce frequency domain distortion sufficient to render any embedded data unrecoverable without introducing significant visually perceptible changes to the source image or image stream.

摘要： A computer-implemented image processing method and apparatus for warping a plurality of gel electrophoresis images is provided. The method includes the steps of assigning tiepoints in a reference image and in one or more object images. The tiepoints in the object image are evaluated one-by-one by comparison to regions about a corresponding tiepoint in the reference image, and the location of the tiepoint in the object image is adjusted by slight movement to a location with respect to recognizable features in both the reference and object image thereby defining a tiepoint pair linking a location in the reference image with a location in the object image. outlier tiepoint pairs may be rejected if that pair does not meet predetermined conditions. Warping functions are generated and then globally optimized. The plurality of images are tied together using the tiepoint pairs such that all of the images may be subsequently warped into registration to a single base image selected from the plurality of images.

摘要： The invention aligns a set of plural images to construct a mosaic image. At least different pairs of the images overlap partially (or fully), and typically are images captured by a camera looking at the same scene but oriented at different angles from approximately the same location or similar locations. In order to align one of the images with another one of the images, the following steps are carried out: (a) determining a difference error between the one image and the other image; (b) computing an incremental rotation of the one image relative to a 3-dimensional coordinate system through an incremental angle which tends to reduce the difference error; and (c) rotating the one image in accordance with the incremental rotation to produce an incrementally warped version of the one image. As long as the difference error remains significant, the method continues by re-performing the foregoing determining, computing and rotating steps but this time with the incrementally warped version of the one image.

摘要： The line-data generating unit of this apparatus automatically reads a map image through an image scanner, generates a digital-image signal in a pattern-recognition module, prepares line data in a line-data image processing unit, and stores the line data in RAM (I). A data converter retrieves the line data from the line-data generating unit, prepares plane data, and issues the plane data to a property-data preparation unit. Through a closed-area-data image processing unit, the property-information preparation unit, based on instructions input from a keyboard, interpolates points of discontinuity in the plane data; assigns properties corresponding to such points, and prints the output. RAM (II) stores completed data. The interpolation of points of discontinuity in the plane data is performed jointly and simultaneously by input terminals PCi (i=1, 2, . . . , n). Using this method, accurate plane data can be easily and rapidly prepared by reading an original topographical map or the like so that vector line-data is transformed into plane data whose points of discontinuity have been corrected-thus making the plane data completed and accurate.

摘要： An improved method of making a larger map from individual 7.5 minute digital line graph (DLG) data is described herein. The process is fully automated and performed by a computer with minimal human interaction required. This eliminates errors and produces a more accurate final map product. The method includes conversion of the raw DLG data files into ARC/INFO format, locating the border arcs of each individual data set, edgematching the individual map data sets, and joining the data sets into a single, large map coverage. Any node along the border arc which cannot be automatically edgematched is noted in a special error file. A geographer then matches the unmatched edges which contain an error in the input data. A large map product is available as the product of the process.

摘要： Images representing one and the same scene, but acquired under conditions such taht the subject has moved, are automatically reset by making an automatic selection of a homogenous population of landmarks and by computing the shift vectors associated with these landmarks. It is shown that, in order to select the landmarks, it is worthwhile to characterize the image by a certain number of characteristic mangitudes representing the solidity of these landmarks. The solidity of the landmarks is the ability of a landmark to be the site of an exact measurement of shift for a required precision.
