摘要： A system and method for identifying objects, particularly vehicles, between two non-overlapping cameras. More specifically, the method and system determines whether a vehicle depicted in an image captured by a first camera is the same vehicle or a different vehicle than a vehicle depicted in an image captured by a second camera. This intra-camera analysis determines whether the vehicle viewed by the first camera is the same as the vehicle viewed by the second camera, without directly matching the two vehicle images, thus eliminating the problems and inaccuracies caused by disparate environmental conditions acting on the two cameras, such as dramatic appearance and aspect changes.

摘要： Systems, methods, computer-readable media, and graphical user interfaces for facilitating advertisement placement over video content are provided. Images within a video are partitioned into image regions. Upon partitioning images into image regions, an intrusiveness score is determined for each image region. Based on the intrusiveness scores, optimal placement of an advertisement within the video is determined.

摘要： A method and a system for progressive stereo matching of digital images representing a scene. In general, the present invention uses a progressive iterative technique that includes a disparity gradient limit principle and a least commitment strategy. The progressive iterative technique finds generally unambiguous pixel matches by beginning with a few reliable pixel matches and finding progressively more unambiguous pixel matches. Unambiguous pixel matches found in the previous iteration are used to define the search ranges for each pixel to guide matching in the current iteration. Unambiguous pixel matches in the current iteration then are found using a novel correlation technique and based on a correlation score associated with a pixel match. The search range is capable of being rotated, and is part of a novel correlation technique of the present invention that provides a more robust estimate of pixel match reliability. Potential pixel matches found in the search ranges are tested for ambiguity and any unambiguous matches are selected and added to the set of reliable pixel matches. The ambiguity testing includes determining a correlation score for the pixel match and classifying the match based on the correlation score. The present invention also includes a system for progressive image matching that incorporates the method of the present invention.

摘要： The present invention is embodied in a system and method for curve matching multiple images of a scene. The curve matching produces a geometrical representation of the scene from the images, which can be used for any suitable application, such as computer and stereo vision applications. In general, first, multiple images depicting a scene are digitally received by the system. The images are graphical images digitally received and processed as two dimensional image data, such as bitmap or raster image data. Curve matching of the images is then performed to correlate the two images of the scene for creating three dimensional (3D) curve information, such as 3D vector information, of the scene. This 3D vector information can then be used in any suitable manner, for example, to digitally reconstruct the scene for stereo vision applications.

摘要： Methods and computer storage media for creating contextual-display advertisements are provided. A request for a contextual-display advertisement to be presented on a page is received. Upon receiving the request, the page is evaluated to determine the context of the page so that the resulting advertisement is contextually related to the requesting page. The contextually related text and base image are extracted from their respective database to be merged into a contextual-display advertisement. The visual characteristics of the advertisement text are manipulated to provide visual congruity among the elements of the advertisement. Additionally, the placement of the text on the base image is optimized to provide a contextual-image advertisement that is then rendered to be presented on the requesting page.
