Patent number: 8014035Abstract: What is disclosed is a novel system and method for encoding/decoding data in a cover contone image via halftone dot orientation modulation. Arrays of halftone threshold values are used to determine a desired orientation, e.g. 0/90°+/?45° for a given single data value of the original message to be embedded. Message data is embedded as a function of halftone dot orientation. Detection modeling of the print-scan process enables the determination of dot orientation from the image scan via statistically motivated image moments. A probabilistic model of the print-scan channel conditions received moments on input orientation. Density values of the received moments are used to determine dot orientation for each halftone cell. The embedded data is retrieved based on the determined orientations. The present method is applicable to areas of data embedding, document security, and the like.Type: GrantFiled: September 10, 2008Date of Patent: September 6, 2011Assignee: Xerox CorporationInventors: Vishal Monga, Gaurav Sharma, Orhan Bulan

Patent number: 7809179Abstract: A process is provided for inspecting an absorbent article constructed from multiple components. A filtered image is produced from the absorbent article. In the image of the absorbent article, a nonlinear first edge and a second edge are identified at a location where there is a course change in contrast. A center point and centerline of the absorbent article is calculated using the position of the first edge and the second edge. A skew of the absorbent article is calculated. These known locations are utilized to define at least one additional region of the image for further analysis. A third edge and fourth edge are identified at a location where there is a fine change in contrast. The skew of the third edge and the fourth edge within the defined region is calculated and compared to known parameters for the absorbent article.Type: GrantFiled: September 6, 2006Date of Patent: October 5, 2010Assignee: The Procter & Gamble CompanyInventors: Rajesh Kumar Singh, Thomas Keith Olschner, Ian James Semple, Paul Anthony Powell, Jeremy Georges Bertin

Patent number: 7809173Abstract: When detecting a face included in an input image by use of at least two inclinations of the face to be detected, a first detection process is performed if the inclination of the face to be detected corresponds to a first inclination where a relatively high face detection probability is expected, and a second detection process having a relatively low face detection probability and a relatively short processing time compared with the first detection process is performed if the inclination of the face to be detected is other than the first inclination. When an input image is scanned to enable the change in face detection processes according to the position of the face to be detected, a different detection process is used according to the face detection probability of the position of the face to be detected.Type: GrantFiled: October 31, 2006Date of Patent: October 5, 2010Assignee: Fujifilm CorporationInventors: Yoshiro Kitamura, Wataru Ito

Patent number: 7801390Abstract: The apparatus and method of the invention provide for assigning coordinates to samples in an array. The method is based on a hierarchical pattern matching to a local lattice structure that is used as a template. Starting from the best local match, the pattern is expanded hierarchically to encompass the entire array.Type: GrantFiled: November 24, 2008Date of Patent: September 21, 2010Assignee: Carl Zeiss MicroImaging GmbHInventors: Jose De La Torre-Bueno, Peter Salamon

Publication number: 20100215285Abstract: A skewed image data detecting and correcting device includes a skew angle detecting module, and an image rotating correction module. A skewed image data detecting and correcting method includes the following steps. Firstly, a binary digitizing operation is performed to obtain a binary image data. The binary image data is rotated by multiple different rotating angles, thereby obtaining multiple rotated binary image data. The pixel numbers of all horizontal rows of the rotated binary image data are totalized, thereby obtaining multiple horizontal pixel number distribution curves. A high-pass filtering procedure is performed to filter off low-frequency noise, thereby obtaining multiple high-frequency signal curves. The square sums of respective high-frequency signal curves are calculated, thereby obtaining multiple index values.Type: ApplicationFiled: May 28, 2009Publication date: August 26, 2010Applicant: AVerMedia Information, Inc.Inventors: Chien-Hui Tu, Cheng-Yueh Lo, De-Wei Huang, Yung-Hsi Wu

Patent number: 7782361Abstract: A position and an orientation of an image capturing device or an object to which an inclination sensor is mounted are obtained without performing iterative calculation. A position and orientation measuring method includes the steps of: inputting a measured inclination value of an inclination sensor mounted to one of an object and an image capturing device; inputting a captured image from the image capturing device; detecting an index on the object from the captured image; and calculating a position and an orientation of one of the object and the image capturing device to which the inclination sensor is mounted on the basis of the measured inclination value, an image coordinate of the detected index, and already-known positional information on the detected index without performing iterative calculation.Type: GrantFiled: April 5, 2006Date of Patent: August 24, 2010Assignee: Canon Kabushiki KaishaInventors: Daisuke Kotake, Kiyohide Satoh

Patent number: 7778444Abstract: An image processing system (250) and method (300) are disclosed for correcting a head pose in a video phone image, so that a frontal view is presented on a display. A disclosed head pose corrector (250) estimates the orientation of a head pose and adjusts the orientation of the head pose, if necessary, to present a frontal view. The orientation of the head pose is adjusted by generating a three dimensional model of the face surface and adjusting the orientation of the three dimensional face model to provide the desired frontal view. The head pose corrector (250) may be included in a video phone (100) to correct the head pose of transmitted or received images (or both) or may be included in a server on a network to automatically adjust the head shots of one or more participants to a video phone communication.Type: GrantFiled: December 8, 2003Date of Patent: August 17, 2010Assignee: Koninklijke Philips Electronics N.V.Inventors: Mi-Suen Lee, Yun-Ting Lin, Miroslav Trajkovic, Vasanth Philomin
