Abstract: Systems and methods for providing image data/information products to customers are provided. A data management facility generates a graphical user interface that is viewed by customers on computer systems coupled to a processor of the data management facility over a network. The graphical user interface allows a customer to search at least one of stored image data/information products or algorithms, to select at least one of the stored image data/information products or algorithms, and to select a desired geographic location. The data management facility generates a data/information product based on the selected image data/information product and the selected geographic location, and receives a request for an image data/information product, if a desired image data/information product cannot be found in the data management facility. In addition, the processor sends the generated image data/information product to the customer and bills the requestor based on the generated image data product.

Abstract: Red-eye detection based on red region detection with eye confirmation initially identifies pixels that correspond to the color of red-eye within an image. A determination is then made as to whether these identified pixels and surrounding areas are part of an eye or not part of an eye. Those identified pixels that are determined to be part of an eye are the detected red-eye regions.

Abstract: Methods and apparatuses for supporting a color management system that processes an image in accordance to a hierarchically-structured policy are provided. The policy may be modeled with a schema in which the policy is organized with a plurality of policy levels. Policy settings at a lower policy level may override policy settings at a higher policy level, which may be inhibited with a lockout mechanism. A user interface supports the capability of a user configuring policy settings through a series of dialog boxes. The dialog boxes are hierarchically organized in accordance with configuration levels, where the configuration levels are associated with the policy levels. The dialog boxes provide a consolidated approach for configuring a color management system by a user. An interface is supported, enabling a component to send inputs to a color management system in order to configure the policy.

Abstract: Systems and techniques for imaging spectroscopy using improved data acquisition for infrared and near-infrared imaging. A first filter corresponding to a first wavelength may be positioned in the optical path of an infrared camera, and subframe data may be acquired for different exposures. A second filter corresponding to a second different wavelength may be positioned in the optical path of the infrared camera, and subframe data acquired for different exposures. Image data for the first wavelength and the second wavelength may then be compared to reference spectroscopic data.

Abstract: An image processing circuit includes a processor that receives an encoded portion of a first version of an image. The processor decodes this encoded portion directly into a decoded portion of a second version of the image, the second version having a resolution that is different than the resolution of the first version. Therefore, such an image processing circuit can decode an encoded hi-res version of an image directly into a decoded lo-res version of the image. Alternatively, the image processing circuit includes a processor that modifies a motion vector associated with a portion of a first version of a first image. The processor then identifies a portion of a second image to which the modified motion vector points, the second image having a different resolution than the first version of the first image.

Abstract: A digital image that includes first and second regions is processed. An intrinsic color of a given pixel located in an area of interest that is adjacent to at least one of the first and second regions is estimated by extrapolating from colors of multiple pixels in one of the first and second regions and multiple pixels in the other of the two regions.

Abstract: Chromatic bleeding artifacts in a digital image are reduced by modifying chrominance values of at least some pixels in the digital image. The chrominance values are modified according to luminance values and chromatic dynamic range.

Abstract: A method for adjusting saturation of an area of an image is disclosed. The method includes calculating a deviation level of a pixel in the area of the image and calculating a modified saturation value of the pixel in the area of the image according to the deviation level of the pixel in the area of the image and an original saturation value of the pixel in the area of the image. The deviation level indicates brightness differences of the brightness values among the pixel and a pixel set in a vicinity of the pixel in the area of the image. The pixel set includes pixels in the vicinity of the pixel of the area of the image.

Abstract: Systematic use of infrared imaging characterizes marks made on items and identifies the particular marking tool with better accuracy than use of visual imaging. Infrared imaging performed in total darkness eliminates shadows, glint, and other lighting variations and artifacts associated with visible imaging. Although normally used to obtain temperature measurements, details in IR imagery result from emissivity variations as well as thermal variations. Disturbing an item's surface texture creates an emissivity difference producing local changes in the infrared image. Identification is most accurate when IR images of unknown marks are compared to IR images of marks made by known tools. However, infrared analysis offers improvements even when only visual reference images are available.

Abstract: Software of a simple configuration checks whether an original image to be corrected is an image picture, and an image correction process based upon a formed histogram of the original image is not performed for an image different from the image picture. An image processing condition is set in accordance with the formed histogram to perform the image correction process for the original image. An image processing method judges from a shape of the formed histogram whether the original image is an image picture, and does not perform not perform the image correction process for the original image if it is judged that the original image is not an image picture.
