Systems and methods for managing and detecting fraud in image databases used with identification documents

We provide a system for issuing identification documents to a plurality of individuals, comprising a first database, a first server, and a workstation. The first database stores a plurality of digitized images, each digitized image comprising a biometric image of an individual seeking an identification document. The first server is in operable communication with the first database and is programmed to send, at a predetermined time, one or more digitized images from the first database to a biometric recognition system, the biometric recognition system in operable communication with a second database, the second database containing biometric templates associated with individuals whose images have been previously captured, and to receive from the biometric recognition system, for each digitized image sent, an indicator, based on the biometric searching of the second database, as to whether the second database contains any images of individuals who may at least partially resemble the digitized image that was sent. The a workstation is in operable communication with the first server and is configured to permit a user to review the indicator and to make a determination as to whether the individual is authorized to be issued an identification document or to keep an identification document in the individual's possession.

Picture database graphical user interface utilizing map-based metaphors for efficient browsing and retrieving of pictures

In contrast to prior art picture database browsing and retrieving methods which require the tedious opening and perusing of directories, folders and files, the present-inventive graphical user interface system (500) and method produces several display levels (100,200,300,400) of user-friendly geographical / map metaphors from picture metadata with picture icons (116, 216, 316) representing pictures captured at locations on maps. The characteristics of the display levels (100, 200, 300, 400) are programmable by the user. In the preferred embodiment, the size of the picture icons (116, 216, 316) is proportional to the number of pictures captured at the icon location. Further features of the present-inventive graphical user interface (GUI) include a “tool tip” which appears indicating the number of pictures represented by a picture icon (116, 216, 316), when the screen cursor is placed over the picture icon (116, 216, 316). In an example according to the present-inventive GUI, the first display level (100) includes a world map metaphor (114) with picture icons (116) located at the global capture locations of the pictures in the picture database. Each additional display level (200, 300, 400) provides greater geographic specificity of the picture capture locations. Such additional display levels include continent or country of capture (200), state or territory of capture (300), and city or town of capture (400), etc., with the last display level including thumbnail representations (430-448) of the pictures captured at the specified capture locations.

Perceptual similarity image retrieval

A system and method indexes an image database by partitioning an image thereof into a plurality of cells, combining the cells into intervals and then spots according to perceptual criteria, and generating a set of spot descriptors that characterize the perceptual features of the spots, such as their shape, color and relative position within the image. The shape preferably is a derivative of the coefficients of a Discrete Fourier Transform (DFT) of the perimeter trace of the spot. The set of spot descriptors forms as an index entry for the spot. This process repeated for the various images of the database. To search the index, a key comprising a set of spot descriptors for a query image is generated and compared according to a perceptual similarity metric to the entries of the index. The metric determines the perceptual similarity that the features of the query image match those of the indexed image. The search results are presented as a scored list of the indexed images. A wide variety of image types can be indexed and searched, including: bi-tonal, gray-scale, color, “real scene” originated, and artificially generated images. Continuous-tone “real scene” images such as digitized still pictures and video frames are of primary interest. There are stand alone and networked embodiments. A hybrid embodiment generates keys locally and performs image and index storage and perceptual comparison on a network or web server.

Method for computerized indexing and retrieval of digital images based on spatial color distribution

In the context of image database systems, a method for indexing and retrieval of images by their color content and the spatial distribution of color is disclosed. The method is implemented as a software tool that runs on a personal computer and enables the computer to find a desired image from an image database. The user interface allows the user to describe the desired image, and the tool searches the repository for any images that satisfy the description. The description of the composite image may include information on shapes, texture, presence or absence of objects, and color. The process of search and retrieval of images makes use of a method that determines whether a specific color, or a combination of colors, is present in an image. Further, the method determines the location where the specific color or color combination can be found. By analyzing the results of comparisons between the features found in the composite image and in the stored images, the tool retrieves those images that satisfy the description of the query, image. Calculation of color-related features makes significant use of the calculations that are made in the process of image compression which is an essential step prior to image storage. The process of search and retrieval on the basis of features relating to color are provided via a library of routines that perform the necessary tasks.
