An object detection system for detecting instances of an object in a digital image includes an image integrator and an object detector, which includes a classifier (classification function) and image scanner. The image integrator receives an input image and calculates an integral image representation of the input image. The image scanner scans the image in same sized subwindows. The object detector uses a cascade of homogenous classification functions or classifiers to classify the subwindows as to whether each subwindow is likely to contain an instance of the object. Each classifier evaluates one or more features of the object to determine the presence of such features in a subwindow that would indicate the likelihood of an instance of the object in the subwindow.

Business concept definitions may be utilized with software applications, components, tools, and system software. The business concepts definitions are each associated with archetypal definitions, which may also be known as innate concepts. These archetypal definitions may include a person, an organization, a system, a place, an activity, a document, a conceptual object, a physical object, and a category. The business concept definitions may also be represented by an image on a user interface, where the images may be selectable by a user. These business concept definitions may be manipulated and modified. Indeed, certain relationships may be denoted between business concept definitions through the positioning of the images on a user interface. Because these business concept definitions are associated with archetypal definitions, which may be intuitive for users, application definitions using these business concept definitions may be easily created by a user without programming skills.

To produce a black body angiographic image representation of a subject (42), an imaging scanner (10) acquires imaging data that includes black blood vascular contrast. A reconstruction processor (38) reconstructs a gray scale image representation (100) from the imaging data. A post-acquisition processor (46) transforms (130) the image representation (100) into a pre-processed image representation (132). The processor (46) assigns (134) each image element into one of a plurality of classes including a black class corresponding to imaged vascular structures, bone, and air, and a gray class corresponding to other non-vascular tissues. The processor (46) averages (320) intensities of the image elements of the gray class to obtain a mean gray intensity value (322), and replaces (328) the values of image elements comprising non-vascular structures of the black class with the mean gray intensity value.

An apparatus, method, and computer program product are provided for generating an image representation. The method includes receiving an input digital image, extracting features from the image which are representative of patches of the image, generating weighting factors for the features based on location relevance data for the image, and weighting the extracted features with the weighting factors to form a representation of the image.

An apparatus for computed tomography (CT) imaging of a cyclically moving organ includes a positional state monitor (24, 40) that monitors a positional state of the cyclically moving organ such as the heart. A cone-beam CT scanner (10) acquires image data at least within a plurality of time windows. Each time window is centered about an occurrence of a selected positional state of the organ. A window analyzer (38) selects a data segment within each time window such that the data segments combine to form a complete data set covering a selected angular range. A reconstruction processor (44) reconstructs the selected data segments into an image representation.

The present invention is an imaging device which can be equipped with decode functionality and which can be configured to operate in at least one of four user selected modes. In a first, “message only” mode, the device stores into a designated memory location a decoded-out message corresponding to a decodable indicia. In a second, “image only” mode, the device stores into a designated frame storage memory location an image representation of a scene. In a third, “omage plu message” mode the device stores into a designated frame storage memory location an image representation comprising a representation of a decodable symbol and into the same or other memory location the decoded-out message decoded from the decodable indicia, or data corresponding to the same. In the fourth, “two-step message and image” mode, the device is controlled to capture an image a first time for decoding a decodable indicia and a second time for capturing an image that is associated with the decoded-out message corresponding to the decodable indicia.

Security of photographic identification documents is enhanced by providing machine-readable information that may be correlated to other information pertaining to the individual represented by the image, such other information being, for example, printed on the document adjacent to the photograph.

A method for autostereoscopically producing three-dimensional image information from scanned subpixel extracts uses a multiplex track method (MTV) having a separating raster (TR) obliquely extended with respect to a matrix screen (MB) and an electronic tracking (TS) of viewing areas ibased on two separated image views (L, R), that adjacently disposes two or three subpixels (SP) of each pixel (P) of the two image views (L, R) in the actual subpixel extraction (SPA), continuously and alternatingly preserving each subpixel address and disposes said subpixels (SP) in an overlapping manner on each other with an offset, whereby the resolution loss effects the subpixels (SP) only. The crosstalk resulting from the inclination of the separating raster (TR) is reduced by a special structure of the subpixel extraction (SPA), wherein the resolution homogenisation in two directions of the screen is simultaneously preserved. The formation of the actual subpixel extraction (SPA) is carried out according to multiplex schemes (MUX_i) predetermined according to an observer actual position. One or several observers can be electronically tracked subject to the distance thereof from the matrix screen (MB), and the image representation can be adapted therefor.
