Patent number: 7574047Abstract: A method and system for performing image mark recognition for a document is disclosed. A document is scanned into a digital image. Reference image marks are sensed from the digital image. The reference image marks may include trigger row marks and/or corner/crop marks. Coordinates denoting the location of cells within the digital image are determined base on the locations of the reference image marks. Response marks are evaluated for darkness, opacity, and/or grayness on a pixel-by-pixel basis. The response marks are each assigned a percentage value based on the ratio between a total color value for a cell and a maximum color value for a cell.Type: GrantFiled: October 9, 2007Date of Patent: August 11, 2009Assignee: Educational Testing ServiceInventors: Robert Cichielo, Jeffrey Hoffman

Patent number: 7567708Abstract: This disclosure relates to an image processing apparatus or an image processing method, and takes as its technical problem the fact that conventionally it is difficult to perform a process of carving out a rectangle with high precision in a noisy environment. Therefore, as to an image made by binarizing an original image, histograms of the numbers of horizontal and vertical black pixels thereof are created and trapezoidal approximation is performed on the histograms so as to detect vertex coordinates indicating an extent of a rectangular area in the binary image. An inclination direction of the rectangular area in the extent is detected so that the rectangular area can be detected from the binary image with high precision.Type: GrantFiled: August 22, 2007Date of Patent: July 28, 2009Assignee: Canon Kabushiki KaishaInventor: Kunihiro Yamamoto

Patent number: 7562056Abstract: A system for learning an attention model for an image based on user navigation actions while viewing the image is provided. An attention model learning system generates an initial attention model based on static features derived from the image. The learning system logs the actions of users as they view the image. The learning system identifies from the actions of the users those areas of the image that may be of user interest: After the learning system identifies areas that may be of user interest, the learning system attempts to identify attention objects based on those identified areas. After identifying the user attention objects, the learning system updates the attention model for the image to reflect the additional information provided by the user attention objects.Type: GrantFiled: October 12, 2004Date of Patent: July 14, 2009Assignee: Microsoft CorporationInventors: Wei-Ying Ma, Xing Xie

Publication number: 20090097749Abstract: The definition of regions or volumes of interest and the delineation of objects of interest are important and frequently performed tasks in clinical imaging. However, today's solutions for this task are often time-consuming and cumbersome for the clinician. The present invention provides an alternative approach that is intuitive and works even for noisy images where automatic segmentation approaches usually fail. The disclosed systems and methods automatically translate mouse movements relative to an imaginary x-axis and y-axis into modifications in the threshold and scale (i.e., shape and size) of a boundary delineation, thereby permitting a system user/clinician to rapidly arrive at a desired ROI and/or VOI.Type: ApplicationFiled: March 9, 2007Publication date: April 16, 2009Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.
