Patent number: 8494273Abstract: A computer implemented method for adaptive optical character recognition on a document with distorted characters includes performing a distortion-correction transformation on a segmented character of the document assuming the segmented character to be a candidate character. The method further includes comparing the transformed segmented character to the candidate character by calculating a comparison score. If the calculated score is within a predetermined range, the segmented character is identified with the candidate character. The method may be implemented in either of computer hardware configured to perform the method, or in computer software embodied in a non-transitory, tangible, computer-readable storage medium. Also disclosed are corresponding computer program product and data processing system.Type: GrantFiled: September 5, 2010Date of Patent: July 23, 2013Assignee: International Business Machines CorporationInventors: Dan Shmuel Chevion, Vladimir Kluzner, Asaf Tzadok, Eugeniusz Walach

Patent number: 8326542Abstract: A computer implemented method for retrieving seismic data from a seismic section provided in a bitmap format. The method includes reconstructing a two dimensional matrix of seismic interpolated data in which a value at a given pixel in the matrix is proportional to local density of wiggles in the seismic section with an added value of a previously calculated pixel. The method may be implemented in either of computer hardware configured to perform said method and computer software embodied in a non-transitory, tangible, computer-readable storage medium. Also disclosed are corresponding computer program product and data processing system.Type: GrantFiled: November 19, 2009Date of Patent: December 4, 2012Assignee: International Business Machines CorporationInventors: Dan Shmuel Chevion, Yaacov Navon

Patent number: 7969324Abstract: An automatic vehicular traffic flow control technique defines a controlled area, wherein vehicles belonging to different traffic streams contend for occupancy of a conflict zone. A traversal order is computed for the vehicles in the controlled area, wherein the ordered vehicles are assigned to traverse the conflict zone sequentially in accordance with their respective positions in the traversal order. Tracking and tracked vehicles are designated, wherein a respective tracked vehicle immediately precedes each of the tracking vehicles in the traversal order. The tracking vehicles maintain a specified physical relationship with their respective tracked vehicles until the tracked vehicle has traversed the conflict zone. The speed of the traffic streams is increased as necessary so as to achieve a desired throughput through the conflict zone.Type: GrantFiled: December 1, 2008Date of Patent: June 28, 2011Assignee: International Business Machines CorporationInventors: Dan Shmuel Chevion, Dov Ramm, Yuval Shimony, Ron Sivan

Publication number: 20090189831Abstract: An improved automobile. An exemplary automobile includes an engine, a set of wheels connected to the engine, a chassis connected to the engine, and an electrochromatic windshield connected to the chassis. The electrochromatic windshield is operable to darken and un-darken the electrochromatic windshield. A video projection system is also connected to the chassis. The video projection system is operable by a driver to project an overlay image on the electrochromatic windshield. The electrochromatic windshield can be darkened by activation of the video projection system and un-darkened by deactivation of the video projection system. The video projection system can be used to project a map onto the electrochromatic windshield. The video projection system can then be used to project a relative position of the driver's vehicle, other vehicles and obstructions on the map, as well as highlighting and tracking, via graphical markings, these objects as they enter the windshield's projection plane.Type: ApplicationFiled: January 28, 2008Publication date: July 30, 2009Inventors: Dan Shmuel Chevion, Tal Drory, Yuval Asher Shimony, Ron Sivan

Patent number: 7529542Abstract: Establishing communication between people when face-to-face communication is difficult by pointing a portable device in a direction of a target and recording a position and orientation of the portable device and by recording a distance between the portable device and the target. Further, this communication is established by calculating a location of the target based on the recorded position, orientation, and distance and broadcasting, via the portable device, a message including the calculated location of the target. Moreover, this communication is established when the target receiving the message, compares the calculated location of the target with an actual position of the target to determine whether the target that received the initiation message is within a predetermined proximity of the calculated location of the target. If the receiving target is within the predetermined proximity of the intended target, a reply is transmitted to the portable device to initiate handshaking.Type: GrantFiled: April 21, 2008Date of Patent: May 5, 2009Assignee: International Business Machines CorporationInventors: Dan Shmuel Chevion, Ron Sivan, Sima Nadler
