  • Patent number: 9892585
    Abstract: A document may include a non-magnetic substrate, a first colorant mixture printed as a first image upon the substrate, the first colorant mixture including a magnetic ink, and a second colorant mixture printed as a second image upon the substrate in substantially close spatial proximity to the printed first colorant mixture. The second colorant mixture may consist essentially of one or more non-magnetic inks and exhibit properties of both low visual contrast and high magnetic contrast against the first colorant mixture, such that the resultant printed substrate does not reveal the first image to the human eye, but will reveal the first image to a magnetic image reader.

  • Patent number: 8478079
    Abstract: In this invention, scan conversion processing of changing the scan order for each block is used. Parallel scan conversion processing is executed if possible, thereby making the number of scan conversion target blocks per unit time larger than before. To do this, a scan status holding unit holds statistical information based on the appearance frequency values of coefficients in a block. A scan order holding unit holds coefficient position information in which the coefficient positions in a block are arranged based on the scan order. A parallel number determination unit determines the number of blocks processable in parallel based on the statistical information held in the scan status holding unit and supplies the result to a scan conversion unit as a control signal. If the control signal from the parallel number determination unit indicates parallel processing, the scan conversion unit executes scan conversion of two input blocks in parallel.

A comparative data transform is applied to each set of image data, such that the transformed comparative image data isolates and preserves first variations in the illumination between the images but suppresses second differences in illumination between the images. At least one normalization transform is determined from the transformed comparative image data sets. When applied to at least one of the image data sets, the at least one normalization transform minimizes the variation in illumination between the image data sets.

  • Patent number: 8115439
    Abstract: A system for moving robots in accordance with a predetermined algorithm. The system includes: a surface having a position-coding pattern which identifies the surface; mobile robots for moving across the surface, each robot being configured for sensing and decoding the position-coding pattern; and a computer system in communication with the mobile robots. The computer system is configured to send instructions for moving each mobile robot relative to the surface in response to position information corresponding to that mobile robot. Further, the computer system is configured to determine instructions for moving each mobile robot using a predetermined algorithm. The predetermined algorithm is selected on the basis of the identity of the surface.

  • Patent number: 8111949
    Abstract: A captured image projection apparatus obtains projection parameters and image effect correction parameters from a moving image captured at a low resolution in a task different from a task in which capturing of a high-resolution still image is to be performed, when a change ceases to occur in the moving image and before the capturing of the high-resolution still image is started. The apparatus changes the scale of the obtained projection parameters from one for low-resolution image to one for high-resolution image. The apparatus applies an image conversion process and an image effect process to the captured high-resolution still image by using the projection parameters and image effect correction parameters obtained before the still image is captured. Thereby, the captured image projection apparatus shortens the time required from the capturing of the image to projection thereof.

  • Patent number: 8111433
    Abstract: An image reading device includes a reference member, a reading unit, a first reference value setting unit, a detecting unit, a second reference value setting unit, a determining unit, and a pixel value setting unit. The reading unit obtains image data and reference data. The first reference value setting unit sets a first reference value based on the reference data. The detecting unit detects a usage state of the reading unit. The second reference value setting unit sets a second reference value in accordance with the usage state. If the determining unit determines that the first reference value is in a predetermined condition, the pixel value setting unit sets a pixel value based on the image data and the first reference value; otherwise, the pixel value setting unit sets the pixel value based on the image data and the second reference value.

  • Patent number: 8103109
    Abstract: There is a need to provide simple, accurate, fast and computationally inexpensive methods of object and hand pose recognition for many applications. For example, to enable a user to make use of his or her hands to drive an application either displayed on a tablet screen or projected onto a table top. There is also a need to be able to discriminate accurately between events when a user's hand or digit touches such a display from events when a user's hand or digit hovers just above that display. A random decision forest is trained to enable recognition of hand poses and objects and optionally also whether those hand poses are touching or not touching a display surface. The random decision forest uses image features such as appearance, shape and optionally stereo image features. In some cases, the training process is cost aware. The resulting recognition system is operable in real-time.

  • Patent number: 8019180
    Abstract: A method for constructing arbitrary-plane and multi-arbitrary-plane mosaic composite images from a multi-imager is disclosed. A first homography set is generated for a multi-imager based on a first reference plane. A second homography set is then generated for the multi-imager based on a second reference plane, where the second reference plane is distinct from the first reference plane. The first homography set and the second homography set are then utilized to generate a third homography set for the multi-imager based on an arbitrary plane. In so doing, the arbitrary plane becomes repositionable with respect to a scene that the multi-imager is viewing. Multiple such arbitrary planes may be selected in constructing multi-planar mosaic composite images. Multiple such second reference planes may be presented to provide improved quality derivation of the said third homography set.

  • Patent number: 7969475
    Abstract: Embodiments of the invention are described that provide automated and efficient optimization of camera settings. In certain embodiments of the invention, both focus and exposure settings are determined based on an analysis of compressed images taken of a frame. Based on this analysis, the camera focus and exposure settings are set to provide a preferred image quality of the particular frame. This optimization of the focus and exposure settings is performed at each frame within the multi-frame image source. As a result, each frame image is independently optimized and addresses variations, such as light and surface inconsistencies, across the multi-frame image source.

  • Patent number: 7924477
    Abstract: Images of a document having a surface are captured. In this process, multiple scan lines respectively illuminated from different illumination angles relative to the document surface are scanned across the document surface in a first scan direction in relation to orientation of the document. Multiple scan lines respectively illuminated from different illumination angles relative to the document surface are scanned across the document surface in a second scan direction in relation to orientation of the document. The captured images are generated from scan line illumination reflected from the document surface during the scanning of respective ones of the scan lines across the document surface. A crease or a tear is detected in the document based on the captured images.
