Patent number: 8335355Abstract: A method and system for image recognition in a collection of digital images includes training image classifiers and retrieving a sub-set of images from the collection. For each image in the collection, any regions within the image that correspond to a face are identified. For each face region and any associated peripheral region, feature vectors are determined for each of the image classifiers. The feature vectors are stored in association with data relating to the associated face region. At least one reference region including a face to be recognized is/are selected from an image. At least one classifier on which said retrieval is to be based is/are selected from the image classifiers. A respective feature vector for each selected classifier is determined for the reference region.

Patent number: 8311331Abstract: An optical character recognition process characterizes text lines in a textual image by their base-line, mean-line and x-height. The base-line for at least one text line in the image is determined by finding a parametric curve that maximizes a first fitness function that depends on the values of pixels through which the parametric curve passes and pixels below the parametric curve. The base-line corresponds to the parametric curve for which the first fitness function is maximized. The first fitness function is designed so that it increases with increasing lightless or brightness of pixels immediately below the parametric curve while also increasing with decreasing lightness of pixels through which the parametric curve passes. The mean-line is determined by incrementally shifting the base-line upward by predetermined amounts (e.g., a single pixel) until a second fitness function for the shifted base-line is maximized. The second fitness function is essentially the inverse of the first fitness function.Type: GrantFiled: March 9, 2010Date of Patent: November 13, 2012Assignee: Microsoft CorporationInventors: Djordje Nijemcevic, Milan Vugdelija, Bodin Dresevic

Patent number: 8306270Abstract: A vehicle travel support device determines presence of a recognition inhibiting factor of a lane mark on a road on which a vehicle is traveling with high accuracy irrespective of an imaging history by a vehicular camera from the same position. The vehicle travel support system generates an edge image by extracting an edge or actualizing an edge in an image obtained through the vehicular camera. When Hough transform of the edge image is performed, votes for a specified vote value of a linear component is evaluated in a ?-? space (Hough space). Presence of a recognition inhibiting factor of a lane mark on a road is determined by determining whether or not the votes of a specified vote value in a specified region denoting a standard travel lane of a vehicle in the real space is ?a threshold in the ?-? space.Type: GrantFiled: January 9, 2009Date of Patent: November 6, 2012Assignee: Honda Motor Co., Ltd.Inventor: Hidenori Sato

Patent number: 8306285Abstract: Processing for judging whether a face is included in a frame is performed, in a predetermined interval, on each of frames included in a moving image of a subject, displayed on a monitor, until the judgment becomes positive. If it is judged that a face is included in a frame, the facial position is detected in the frame, and stored. Then, judgment is made as to whether a face is included in the next frame after predetermined time. If the judgment is positive, the facial position is detected. The previously stored facial position is replaced by the newly detected facial position, and the newly detected facial position is stored. These processes are repeated until photographing operation is performed by operating a release unit.Type: GrantFiled: June 27, 2011Date of Patent: November 6, 2012Assignee: FUJIFILM CorporationInventor: Wataru Ito

Patent number: 8290213Abstract: While locating a license plate of a moving vehicle on consecutive images, motion detection is first performed on the consecutive images to detect a moving vehicle image, which is segmented using edge detection, and the segmented moving vehicle image is analyzed to retrieve characteristics for locating a license plate image and determining characters on the located license plate image. As a result, a precise location of the license plate is thus precisely located for further recognition no matter what weathers in which the consecutive images are recorded. The above-mentioned technique requires merely few calculations, is easily implemented, and may be applied on an intelligent digital video recording (DVR) system including many computer-vision functions.Type: GrantFiled: June 4, 2010Date of Patent: October 16, 2012Assignee: Huper Laboratories Co., Ltd.Inventors: Chao-Ho Chen, Chi-Ming Huang, Hui-Pin Huang

Patent number: 8290292Abstract: At least one approximation image is created of the image at one or multiple scales. Translation difference images are created by pixel-wise subtracting the values of an approximation image at scale s and the values of a translated version of the approximation image. A non-linear modification is applied to the values of the translation difference image (s) and at least one enhanced center difference image at a specific scale is computed by combining the modified translation difference images at that scale or a smaller scale with weights wi,,j. An enhanced image is computed by applying a reconstruction algorithm to the enhanced center difference images. The non-linear modification of the values of the translation difference images is steered by (a) characteristic (s) computed out of the approximation image (s) at least one scale.Type: GrantFiled: June 10, 2008Date of Patent: October 16, 2012Assignee: Agfa HealthCare N.V.Inventors: Tom Bertens, Pieter Vuylsteke

Patent number: 8280151Abstract: Display suitable to an actual three-dimensional model or a recognition-target object is performed when stereoscopic display of a three-dimensional model is performed while correlated to an image used in three-dimensional recognition processing. After a position and a rotation angle of a workpiece are recognized through recognition processing using the three-dimensional model, coordinate transformation of the three-dimensional model is performed based on the recognition result, and a post-coordinate-transformation Z-coordinate is corrected according to an angle (elevation angle f) formed between a direction of a line of sight and an imaging surface. Then perspective transformation of the post-correction three-dimensional model into a coordinate system of a camera of a processing object is performed, and a height according to a pre-correction Z-coordinate at a corresponding point of the pre-coordinate-transformation three-dimensional model is set to each point of a produced projection image.Type: GrantFiled: February 23, 2010Date of Patent: October 2, 2012Assignee: Omron CorporationInventors: Shiro Fujieda, Atsushi Taneno, Hiroshi Yano, Yasuyuki Ikeda

Patent number: 8259996Abstract: Hands may be tracked before, during, and after occlusion, and a gesture may be recognized. Movement of two occluded hands may be tracked as a unit during an occlusion period. A type of synchronization characterizing the two occluded hands during the occlusion period may be determined based on the tracked movement of the occluded hands. Based on the determined type of synchronization, it may be determined whether directions of travel for each of the two occluded hands change during the occlusion period. Implementations may determine that a first hand and a second hand are occluded during an occlusion period, the first hand having come from a first direction and the second hand having come from a second direction. The first hand may be distinguished from the second hand after the occlusion period based on a determined type of synchronization characterizing the two hands, and a behavior of the two hands.Type: GrantFiled: October 31, 2007Date of Patent: September 4, 2012Assignee: QUALCOMM IncorporatedInventor: Atid Shamaie
