Patent number: 8705874Abstract: An image processing method and an image processing system using a regionalized architecture are provided. In the method, a plurality of neighborhood pixels having at least one similarity characteristic in an image are classified into a group region having the same characteristics. Then, a unique group mark is assigned to each of the group regions, a regionalized chain code is used to describe an edge of each group region, such that subsequent image processing procedures can be applied to the neighborhood pixels of a currently processed pixel having same group mark. Therefore, the group regions can be recognized according to the group mark and regionalized chain code thereof, so as to simultaneously perform image processing procedures on those group regions.Type: GrantFiled: March 18, 2010Date of Patent: April 22, 2014Assignee: Industrial Technology Research InstituteInventor: Yi-Ta Wu

Patent number: 8693784Abstract: An eyelid detection device that, based on first order differential values and second order differential values of vertical density change at an eyelid boundary in an eye image, shifts the second order differential values upwards by ¼ of the cycle of density change frequency of an eyelid boundary and combines the first order differential values and the second order differential values to compute upper eyelid feature amounts. The eyelid detection device detects a boundary between an upper eyelid and eyeball based on peak points in the vertical direction of the computed upper eyelid feature amounts. Consequently, the boundary between an eyelid and eyeball can be accurately detected even when the eyelid has been applied with makeup.Type: GrantFiled: July 6, 2011Date of Patent: April 8, 2014Assignee: Aisin Seiki Kabushiki KaishaInventors: Akira Kadoya, Satoru Nakanishi, Shinichi Kojima

Patent number: 8660338Abstract: A method for wide baseline feature matching comprises capturing one or more images from an image sensor on each of two or more platforms when the image sensors have overlapping fields of view, performing a 2-D feature extraction on each of the captured images in each platform using local 2-D image feature descriptors, and calculating 3-D feature locations on the ellipsoid of the Earth surface from the extracted features using a position and attitude of the platform and a model of the image sensor. The 3-D feature locations are updated using digital terrain elevation data (DTED) as a constraint, and the extracted features are matched using the updated 3-D feature locations to create a common feature zone. A subset of features from the common feature zone is selected, and the subset of features is inputted into a collaborative filter in each platform. A convergence test is then performed on other subsets in the common feature zone, and falsely matched features are pruned from the common feature zone.Type: GrantFiled: March 22, 2011Date of Patent: February 25, 2014Assignee: Honeywell International Inc.Inventors: Yunqian Ma, Benjamin Mohr

Patent number: 8644575Abstract: According to one embodiment there is provided a computer-automated image processing method applied to a four-dimensional (4D) image data set of a patient's abdomen, e.g. by dynamic contrast enhanced computer-assisted tomography (DCE-CT). One of the three-dimensional (3D) scan images is taken to as the reference volume and the others as target volumes. Before registration between the 3D scan images, the image data set is partitioned into an abdominal cavity domain, containing the organs inside the abdominal wall, and an abdominal wall domain including the abdominal wall and externally adjacent skeletal features, such as the spine and ribs. Registration is then carried out separately on the two domains to obtain two warp fields which are then merged into a 4D image data set of the whole volume for further use, which may be to carry out perfusion measurements, to display and to store the registered 4D image data set.Type: GrantFiled: February 28, 2011Date of Patent: February 4, 2014Assignees: Kabushiki Kaisha Toshiba, Toshiba Medical Systems CorporationInventors: Jim Piper, Ian Poole

Patent number: 8611679Abstract: This invention provides an image processing device and an image processing method capable of implementing pattern matching based on an edge code at relatively high speed with a smaller circuit configuration. In the image processing device according to the present embodiment, an information amount of a valid zone is diffused over an entire edge code image. In other words, the amount of information used in the entire edge code image is compressed by reducing the number of bits to assign to each pixel and effectively using the number of bits assigned to each pixel as a whole. If a valid zone for an edge EDG1, the following invalid zone in which the invalid edge code value continues, and the following valid zone for an edge EDG2 appear in a profile of the edge code value, increase/decrease information from the edge code value contained in the valid zone for the edge EDG1 to the edge code value contained in the valid zone for the edge EDG2 is assigned to the element corresponding to the invalid zone.Type: GrantFiled: February 25, 2010Date of Patent: December 17, 2013Assignee: Omron CorporationInventors: Yutaka Kato, Koji Shimada
