Patent number: 7376249Abstract: The movement of an imaging of a background in a sequence of images of a scene determined. A combination image is composed with pixels which have been built up through combination of several consecutive images.

Patent number: 7231087Abstract: A method for approximating an object's pose from a camera generated image of a scene is performed by first extracting a binary map from the image. The binary map is filtered to include silhouettes of objects located within a predetermined range of distances from the camera. An initial binary shape template may be applied to the binary map to locate potential target object silhouettes. Iterative stages of binary templates are applied to the each target object silhouette that represent a range of poses of the target object. Each stage of templates has higher spatial fidelity than the previous stage and poses corresponding to templates that do not sufficiently match the silhouette are eliminated from consideration. The target object's pose is approximated based on a set of templates that best matches the target object silhouette.Type: GrantFiled: October 29, 2003Date of Patent: June 12, 2007Assignee: Metrica, Inc.Inventor: Eric Huber

Patent number: 6952484Abstract: Disclosed is a method of detecting a predetermined mark embedded in an image. The mark (29) comprises a predetermined arrangement of a plurality of elements (30), each element having a predetermined colour characteristic and predetermined shape. The method processes (20) the image to provide an encoded representation of the image at a predetermined resolution (eg. 200 dpi). The coordinate positions for substantially each of the elements of the mark embedded in the image are detected (22), wherein the detection is characterised by applying at least one mask (80) to substantially each pixel of the encoded representation. From the coordinate positions, a set of spatial features representing a spatial arrangement of the detected elements are then determined (23). The determined set of spatial features is then compared (24) to a known set of spatial features to provide a confidence level measure for a degree of matching between the known set and the determined set of spatial features.Type: GrantFiled: November 16, 1999Date of Patent: October 4, 2005Assignee: Canon Kabushiki KaishaInventors: Paul Raymond Higginbottom, Julie Yan Zhu, Yu-Ling Chen

Patent number: 6859561Abstract: 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: June 1, 2004Date of Patent: February 22, 2005Assignee: International Business Machines CorporationInventors: Joan L.

Publication number: 20040062440Abstract: Sprite identification in animated sequences is achieved by performing three separate but related procedures, namely (i) identification of the sprite, (ii) identification of the background and (iii) identification of the identified sprite's translation path. By analysing a sequence of frames, sprite definition is first established. Then, using the definition of the sprite, a determination is made of the background image and translation path taken. This analysis allows the animated sequence to be compressed in a format in which the background and the sprites are separately identified.Type: ApplicationFiled: October 1, 2002Publication date: April 1, 2004Applicant: International Business Machines CorporationInventor: Deepak M.

Patent number: 5946415Abstract: The processing time and memory in converting scanned images to a hardware scription language is significantly reducer by using a "peephole" method to examine only partial images of features of the scanned image that is to be converted. The present method generated minimized feature templates (MFTs) by systematically removing all non-feature image pixels. In particular, the method and apparatus of the present invention establishes pattern estimates from image samples, eliminates unnecessary image pixels using off-line statistical analysis, and extracts feature templates from the larger size image patterns. Pattern recognition is then conducted by processing a few pixels of the unknown image pattern. An application of this technique is to recognize drawing symbols, such as, AND, NAND, OR, NOR, XOR, and XNOR gates, buffers, inverters, registers, and I/O pins from scanned images of electronic drawings.Type: GrantFiled: October 24, 1996Date of Patent: August 31, 1999Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Wei Su, Gerald T.

Patent number: 5835634Abstract: A bitmap comparison technique that is able quickly to compare two bitmap images while discounting differences between the images likely due to noise. The bitmap comparison technique includes the operations of: comparing the first and second bitmaps, producing a difference map identifying differing bits between the first and second bitmaps, producing outline masks based on the outlines of the first and second bitmaps, identifying certain very different bits within the difference map that are to be weighted differently from the remaining bits within the difference map based upon the outline mask, and determining a comparison score to indicate the extent to which the first and second images differ by differently weighting the very different bits and the remaining bits. The certain bits are normally weighted to a lesser extent than the remaining bits when determining the comparison score so that the influence of noise in the comparison score is diminished.Type: GrantFiled: May 31, 1996Date of Patent: November 10, 1998Assignee: Adobe Systems IncorporatedInventor: Kenneth A.

Patent number: 5671292Abstract: A high speed digital image pattern matching circuit which recognizes an image pattern, and discriminates whether the recognized image pattern matches with a desired reference pattern and where pattern matching occurs. For discriminating whether a desired pattern is matched, an input pattern to be retrieved is digitally-modelled as two thresholds. The digitally modelled input image signal is blocked to have the same size as the reference pattern and compared with the reference pattern. The compared result is again compared with the thresholds for discriminating whether pattern matching occurs or not. The high speed digital image pattern matching circuit of the present invention utilizes two thresholds for modelling, thereby simplifying the input digital image signal in hardware and making processing speed very fast.Type: GrantFiled: June 7, 1995Date of Patent: September 23, 1997Assignee: Hyundai Electronics Industries Co., Ltd.Inventors: Young Lee, Nam-Soo Moon
