Patent number: 7620244Abstract: Various computer-implemented methods are provided. One method for signature recognition includes identifying a vertical element of a signature and determining a tilt angle of the vertical element. Tilt angle is defined by a line that is approximately parallel to the vertical element. In addition, the method includes determining a tilt factor. Tilt factor is defined as a horizontal offset between the tilt angle and a reference tilt as a function of distance from a signature baseline. The method further includes altering the signature using the tilt factor and comparing the altered signature to known signature(s) to determine if the altered signature matches one of the known signature(s). Another method includes altering the signature using a predetermined tilt factor and comparing the altered signature to known signature(s). If the altered signature does not match one of the known signature(s), these steps may be repeated with different predetermined tilt factors.Type: GrantFiled: January 6, 2004Date of Patent: November 17, 2009Assignee: Motion Computing, Inc.Inventor: David C.

Patent number: 7587086Abstract: The present application provides for accurately identifying a selection of pixels in a digital image. A pixel edgewalk procedure utilizes pixel reference points situated around a pixel, such as at pixel vertices, to determine where to draw an outline to encompass selected pixels. Each pixel reference point is represented by one or more bits in memory that indicate certain information about each particular pixel reference point and pixels surrounding the pixel reference point. Utilizing this information, a determination is made as to where an outline can be drawn according to certain pixel reference points to encompass only pixels that are selected pixels. Resource overhead for determining bit settings for some pixel reference points is reduced by utilizing a bit-wise shift in memory bits allocated to an adjacent pixel reference point.Type: GrantFiled: June 4, 2004Date of Patent: September 8, 2009Assignee: Microsoft CorporationInventor: Sergei S Shinkevich

Patent number: 7580559Abstract: A method and system as used to calibrate a reflective SLM. The system can include the SLM having an array of pixels and a projection optical system resolving individual pixels and having an apodized pupil. During a calibration operation, the pixels of the SLM receive varying voltage values to move them through various angles. Light reflecting from the pixels during these movements forms individual images for each pixel at each angle. The light passes through the apodized pupil and is received on one or more sections of a detector. The apodization pattern is selected so that individual pixels remain well resolved with strong sensitivity to the pixel mirror tilt. The light intensity received for each pixel at each angle is correlated to the voltage value received at the pixel to tilt the pixel to that angle producing a result signal used by a control device to calibrate the SLM.Type: GrantFiled: January 29, 2004Date of Patent: August 25, 2009Assignee: ASML Holding N.V.Inventors: Azat M.

Patent number: 7565031Abstract: A method is proposed which enables high-resolution raster images to be represented on lower-resolution displays. The method according to the invention selects support points in lines and columns of the original image, which have a smallest possible variation of their distances and approximate the set scaling at least in ranges. Consequently, rational scaling ratios can also be achieved in an advantageous manner. In order to represent fine details of the original image in the scaled image as well, the adjacent pixels of the support points are also incorporated into the calculation of the pixels that are output. Furthermore, a circuit for scaling a raster image in real time is proposed. Moreover, a film scanner having a scaling device in accordance with the method according to the invention is proposed.Type: GrantFiled: March 23, 2004Date of Patent: July 21, 2009Assignee: Thomson LicensingInventor: Andreas Loew

Patent number: 7558402Abstract: A system and method for tracking a global shape of an object in motion is disclosed. One or more control points along an initial contour of the global shape are defined. Each of the one or more control points is tracked as the object is in motion. Uncertainty of a location of a control point in motion is represented using a number of techniques. The uncertainty to constrain the global shape is exploited using a prior shape model. In an alternative embodiment, multiple appearance models are built for each control point and the motion vectors produced by each model are combined in order to track the shape of the object. The movement of the shape of the object can be visually tracked using a display and color vectors.Type: GrantFiled: March 5, 2004Date of Patent: July 7, 2009Assignee: Siemens Medical Solutions USA, Inc.Inventors: Xiang Sean Zhou, Dorin Comaniciu, Bogdan Georgescu, Sriram Krishnan

Patent number: 7551768Abstract: In an image recognition method, the image of a cream solder 9 printed on a rectangular electrode 16 having a solder leveler formed is picked up and recognized to identify the cream solder 9. An illuminating unit having white light source parts 35W arranged in the radial oblique directions of 45° is used to apply white color illumination lights from a light applying direction in which an angle of ?1 formed by the light applying direction and a horizontal plane in a vertical plane is 45° or smaller and from a light applying direction in which an angle of ?3 formed by the light applying direction and the boundary of the electrode 16 in a horizontal plane is 75° or smaller. Thus, regularly reflected lights from a solder leveler forming surface 16a with a glossiness are not received by an upper camera to identify a solder surface 9a and the solder leveler forming surface 16a with good accuracy.Type: GrantFiled: January 8, 2004Date of Patent: June 23, 2009Assignee: Panasonic CorporationInventors: Yasuichi Okada, Kimiyuki Yamasaki, Masahiro Kihara

Patent number: 7529410Abstract: A technique is disclosed for determining a portion of a document corresponding to a captured image. A user employs a pen to create a stroke in a document, and images are captured by a camera mounted on the pen. The locations of some of the images are determined by, e.g., analyzing a pattern on the document captured by the image or by a pixel-by-pixel comparison of the image with the document. The locations of other images are determined by segmenting the sequence of images into groups corresponding to the shape of the stroke. Information relating to a located image in a segment is employed to determine the position of an unlocated image in the segment. This determined position is used for obtaining further information that may be used to determine the position of another unlocated image in the segment, and so on, until the segment is finished.Type: GrantFiled: January 7, 2004Date of Patent: May 5, 2009Assignee: Microsoft CorporationInventors: Jian Wang, Yingnong Dang, Qiang Wang, Liyong Chen, Xiaoxu Ma
