Patent number: 6822248Abstract: Fine positioning of a shaped or patterned charged particle beam without use of intrusive fiducial marks is achieved by providing a dithered shadow pattern, preferably in the form of a grid, within the shaped or patterned charged particle beam. Light output from fiducial marks preferably formed of a scintillating material is reduced when the dithered shadow pattern is incident on some or all of the fiducial marks. The timing of the incidence of the shadow pattern on fiducial marks indicates the position of the shaped or patterned charged particle beam such that correction of the beam position on the target can be corrected to a small fraction of system resolution. The dither pattern and repetition period is chosen to avoid interference with uniformity of beam illumination of the target. Feedback of position error thus provides phase locked position correction in real time and is suitable for mask making since the fiducial marks are not intrusive.Type: GrantFiled: March 15, 2001Date of Patent: November 23, 2004Assignee: International Business Machines CorporationInventors: Juan Ferrera, James G. Goodberlet, Timothy R. Groves, John G. Hartley, Mark K. Mondol, Mark L. Schattenburg, Henry I. Smith

Patent number: 6819803Abstract: Image rotations of 90°, 180° and 270° and horizontal and vertical mirroring image transformations are performed losslessly and with greatly enhanced speed by processing orthogonal transform coefficients in a zig-zag order with direct storage of S (size) values, reassociated R (run of zero valued coefficients) from an adjacent coded orthogonal transform value and a non-zero valued transformation coefficient in reverse zig-zag order. Cache misses are avoided by processing values which are not widely separated in the coded data and other features of the technique and memory accesses are reduced to accelerate processing while extremely little computation is required. These effects are substantially augmented when intermediate codes having certain attributes including coding of zero valued coefficients and flagging certain code features are employed.Type: GrantFiled: July 2, 2001Date of Patent: November 16, 2004Assignee: International Business Machines CorporationInventors: Joan L.

Patent number: 6813607Abstract: A computer implemented method in a language independent system generates audio-driven facial animation given the speech recognition system for just one language. The method is based on the recognition that once alignment is generated, the mapping and the animation hardly have any language dependency in them. Translingual visual speech synthesis can be achieved if the first step of alignment generation can be made speech independent. Given a speech recognition system for a base language, the method synthesizes video with speech of any novel language as the input.Type: GrantFiled: January 31, 2000Date of Patent: November 2, 2004Assignee: International Business Machines CorporationInventors: Tanveer Afzal Faruquie, Chalapathy Neti, Nitendra Rajput, L.

Patent number: 6807634Abstract: A digital watermarking method encodes different pairs of watermarks into each of a plurality of images offered for use by a vendor. The watermarks in each pair are derived from two separate collections of watermarks and sufficiently different so as to prevent false positives. Because each pair of watermarks is assigned to a different customer relative to a particular image, unauthorized use of a digital image sold to a customer may be determined by locating the associated pair of watermarks assigned to the customer in the image. Collusion detection is also realized by forming each pair of masks from sub-collections of masks which are detectable in an image formed by combining the same images sold to one or more customers.Type: GrantFiled: November 30, 1999Date of Patent: October 19, 2004Assignee: International Business Machines CorporationInventors: Gordon W. Braudaway, Marco Martens, Frederick C. Mintzer, James B. Shearer, Charles P. Tresser, Chai W. Wu
