  • Patent number: 7379574
    Abstract: A method to quantify the vascular irregularity of aortoiliac arteries is provided. Inner wall and/or outer wall outlines of a vessel of interest are determined. The cross sectional area is determined for the area outlined by each outline. Using this cross sectional area a shape is selected that has substantially the same area as the outline. Subsequently, the shape is fitted to the outline. In one aspect, the irregularity index is calculated as the ratio of the outline and the outline of the fitted shape. In another aspect, the irregularity index is calculated as the ratio of at least a part of the outline and the outline of the fitted shape that corresponds to the same part of the outline. The irregularity index is visualized using a color scheme, a range of numbers, or a set of labels.

  • Patent number: 7349567
    Abstract: The present invention is operative to determine the angular pose of an assumed object. A series of projection sums are calculated from a sample image of the known object where the known object has an assumed pose. The projection sums are calculated for a range of angles and organized into a two dimensional array coined a projection image. An image of the known object is provided where the known object has an unknown pose. A projection sum is calculated across the image of the known object with the unknown pose preferably at the perpendicular. This projection sum is correlated against the projection image and the angle corresponding to the best correlation is determined to be the angular pose of the known object.

  • Patent number: 7343051
    Abstract: A method of recognizing an object in an image using multi-sensor integration through conditionally optimal geoscene generation and registration is provided. At least two images, one of which is a conditionally optimum, ortho-rectified base image, are input and used to generate a geoscene using at least two ground control points in a latitude-longitude geospatial domain. Georegistration of the geoscene produces a registered geoimage which may be output. A virtual geospatial information system database may be compiled from the georegistered images. A virtual transverse Mercator (VTM) projection is defined which allows processing images falling on both sides of the equator or across traditional UTM boundaries. An Affine transform is used for coordinate transformation in generating geoscenes.

  • Patent number: 7289658
    Abstract: A method for reducing a number of shapes, and a computer readable program code adapted to perform said method. The method forms first and second shape patterns. The second shape pattern includes the first shape pattern and error shapes. The error shapes are extracted from the second shape pattern. At least one environment shape corresponding to each error shape is derived from a subset of the error shapes. For example, each error shape in the subset may be expanded to form a corresponding expanded shape, and at least one environment shape corresponding to each expanded shape may be formed by removing all portions of the expanded shape common to the second shape pattern. The environment shape reflects a local geometric environment of its corresponding error shape. A subset of the environment shapes are deleted such that only unique environment shapes satisfying a selection criterion remain.

  • Patent number: 7286691
    Abstract: The present invention relates to devices and a method for biometric authentication by means of reference data stored in a memory of a portable data carrier. For biometric authentication methods to make their final breakthrough with respect to more widespread use, there is a need for standardized generation of reference data for the particular biometric features used for authentication. Different suppliers of methods and devices for biometric authentication have hitherto used algorithms for generating the reference data which normally lead to different reference data which are not interchangeable. This limits the employability of biometric methods to the supplier's particular system. The present invention avoids this problem by storing several sets of biometric reference data, thereby increasing the likelihood of the evaluation of at least one set of stored biometric reference data being possible. Thus, the desired system-independent authentication can be attained.

  • Patent number: 7286690
    Abstract: Prestack seismic data is imaged by calculating an individual reflectivity for each frequency in the seismic data. Then, a mean reflectivity is calculating over the individual reflectivities. A variance is calculated for the set of reflectivities versus frequency. A second variance is calculated for the upgoing wavefield, using the mean reflectivity. A spatially varying pre-whitening factor is then calculated, using the variance for the reflectivities and the variance for the upgoing wavefield. A reflectivity is calculated at each location, using the spatially varying pre-whitening factor.

  • Patent number: 7280705
    Abstract: A digital imaging system includes an image sensor, a frame buffer and a tone correction circuit. The tone correction circuit computes tone corrected pixel data using one or more tone correction curves. In operation, tone corrected pixel data for a first pixel is computed by generating a pixel mask for an m×n neighborhood of pixels surrounding the first pixel, applying a blending mask of weight factors to the pixel mask and computing a selector value based on the pixel mask and weight factors associated with the blending mask. The selector value is used to derive a first tone correction curve for use to compute the tone corrected pixel data for the first pixel. The first tone correction curve can be selected from the multiple tone correction curves based on the selector value or it can be derived by blending multiple tone correction curves based on the selector value.

  • Patent number: 7274811
    Abstract: Certain embodiments of the present invention provide a system and method for automatically synchronizing multiple images. Multiple image sets of a single object are converted into a one dimensional data stream used to synchronize multiple image sets. A common reference point is located in the image sets. Various landmarks of the object are also located in the image sets. Corresponding landmarks among the image sets are noted. Distances from landmarks to the reference point and distances between landmarks are determined. Locations of the landmarks in relation to each other and in relation to the reference point are used to locate landmarks in another image set that correspond to landmarks in a selected image set. A first location in an image set may be identified using a first indicator. A second indicator corresponding to the location of the first indicator may then be determined in another image set.
