Patent number: 7945113Abstract: A technology is provided whereby correction may be carried out appropriately for both a person's face and other portions of an image, when performing color correction for image data of a photographic image in which a person appears. A process such as the following is carried out during color correction of image data of a photographic image. First, the image data of the photographic image is analyzed, and a first region which is part of the photographic image and in which a person's face is present is determined. Then, on the basis of the portion corresponding to the first region of the image data, a first parameter relating to color is calculated. On the basis of part of the image data corresponding to a second region which is part of the photographic image but different from the first region, a second parameter relating to color is calculated. The color tone of the data is then corrected on the basis of the first and second parameters.Type: GrantFiled: February 21, 2007Date of Patent: May 17, 2011Assignee: Seiko Epson CorporationInventor: Ikuo Hayaishi

Patent number: 7899232Abstract: A method and apparatus for testing luggage screening equipment operators is provides. A sequence of images of contents of luggage items derived from a device that scans the luggage items with penetrating radiation are received. The image generation device is characterized by introducing a certain distortion into these images of contents of luggage items. A display device is caused to display images derived from this sequence of images. Occasionally, the display device is caused to show a simulated threat in a luggage item by displaying a combined image derived based at least in part on an image in the sequence of images and a distorted threat image. The distorted threat image was derived by applying a distortion insertion process to a reference threat image wherein the distortion insertion process tends to approximate the certain distortion introduced in the images of contents of luggage items by the device that scans the luggage items with penetrating radiation.Type: GrantFiled: May 11, 2007Date of Patent: March 1, 2011Assignee: Optosecurity Inc.Inventors: Dan Gudmundson, Luc Perron, Alexandre Filiatrault, Aidan Doyle, Michel Bouchard

Patent number: 7120313Abstract: Plural pieces of frame data are generated and held based on image data obtained by capturing images while moving a plurality of capture devices for capturing images in different directions. A frame data group containing consecutive pieces of frame data determined to have been captured at practically the same position can be extracted from the plural pieces of held frame data. Frame data is deleted from the extracted frame data such that one piece of frame data can exist as the data captured at one position. Thus, when the frame data corresponding to a plurality of positions on a map is stored, thinned frame data is stored after being associated with the corresponding position on the map. Therefore, when virtual space in a walk-through system is designed using an IBR technology, panoramic images for reproduction of the virtual space can be efficiently generated and held.Type: GrantFiled: March 28, 2001Date of Patent: October 10, 2006Assignee: Canon Kabushiki KaishaInventors: Daisuke Kotake, Akihiro Katayama

Patent number: 7103235Abstract: A method and apparatus for processing imagery using images acquired via any known Electro-Optical (EO) system. In accordance with exemplary embodiments of the present invention, a first frame of data is selected as a template frame (e.g., a given frame). A second frame of data can be captured using the EO system. At least a portion of the second frame can be correlated with the template frame to generate a shift vector. The second frame can then be registered with the template frame by interpolating the second frame using the shift vector and re-sampling at least a portion of the second frame to produce a registered frame. The template frame can also be re-sampled. The registered frame and the re-sampled template frame can then be combined to generate an averaged frame. The averaged frame can be spatially filtered to enhance edges within the averaged frame.Type: GrantFiled: April 25, 2001Date of Patent: September 5, 2006Assignee: Lockheed Martin CorporationInventors: Gene D.

Patent number: 7020352Abstract: A photo extraction technique is provided that scans film contained within a holder designed to accommodate that particular size and type of film and generates a low-resolution scan of the film and holder. The low-resolution scan is then processed by detecting the borders of the holder, applying a smoothen filter, detecting edge segments of the image-holding areas in the holder, identifying each of the image-holding areas, determining the orientation of the image-holding areas and correcting the orientation thereof if necessary, and locating each of the individual photos within the image-holding areas. Having identified and extracted the photos, an index page comprising thumbnail images of the photos is generated. From this page, the user can select one or more of the images to be printed or displayed in high-resolution.Type: GrantFiled: May 25, 2001Date of Patent: March 28, 2006Assignee: Seiko Epson CorporationInventors: Aindrais O'Callaghan, Anoop Bhattacharjya, Hakan Ancin
