20100088415 | METHOD AND APPARATUS FOR LOCATING FACILITIES - A method and apparatus for providing facility location plans for a network are disclosed. For example, the method identifies a facility and a number of nearest active clients associated with a minimized cost per unit demand of connecting these clients to this facility. The method then connects the number of nearest active clients to the facility associated with the minimized cost per unit demand. In one embodiment, the method iterates this process with the remaining clients until all demands have been assigned to facilities. | 04-08-2010 |
20100169891 | METHOD AND APPARATUS FOR LOCATING LOAD-BALANCED FACILITIES - A method and apparatus for providing a facility location plan for a network with a V-shaped facility cost are disclosed. For example, the method receives an event from a queue, wherein the event comprises an open event or a tight event. The method connects a plurality of adjacent clients to a facility, if the event comprises the open event, and adds a new client-facility edge to a graph comprising a plurality of client-facility edges, if the event comprises the tight event. | 07-01-2010 |
20110012898 | Global Registration of Multiple 3D Point Sets Via Optimization on a Manifold - A method for registering multiple 3D point sets by determining optimal relative positions and orientations of the 3D point sets. Initial values are determined for the rotation matrices corresponding to the relative orientations of reference frames of the 3D point sets. A registration error cost function is optimized on a product manifold of all of the rotation matrices to determine optimal values of the rotation matrices. The optimal values of the rotation matrices are used to determine optimal values for translation vectors corresponding to the relative positions of the reference frames of the 3D point sets. The 3D point sets are registered on a common reference frame using the optimal rotation matrices and the optimal translation vectors. | 01-20-2011 |
20130121568 | System and Method of Image Upsampling - A method includes receiving an image having a first resolution and generating an upsampled image having a second resolution based on the image. A multi-dimensional data structure corresponding to a multi-dimensional image space is generated from the upsampled image. Each node of the data structure is determined based on a weighted sum of values of one or more pixels in the upsampled image. Each of the one or more pixels corresponds to a pixel in the received image and is located within a region of the image space having a vertex defined by the node. A filter modifies the values of the nodes and a second upsampled image is generated based on the modified values of the nodes. Each pixel of the second upsampled image not corresponding to a pixel in the received image is determined based on a weighted sum of the modified values of one or more nodes. | 05-16-2013 |
20130336585 | SYSTEM AND METHOD OF BILATERAL IMAGE FILTERING - A method includes generating a first principle bilateral filtered image component from a source image. The first principle bilateral filtered image component corresponds to a second pixel value of a set, the second pixel value greater than or equal to a first pixel value. The method includes selectively updating a result pixel of a result image based on the first principle bilateral filtered image component and deallocating the first principle bilateral filtered image component. After deallocating the first principle bilateral filtered image component, a second principle bilateral filtered image component is generated from the source image. The second principle bilateral filtered image component corresponds to a third pixel value. The third pixel value is greater than the second pixel value. The third pixel value is less than or equal to a fourth pixel value. The result pixel is selectively updated based on the second principle bilateral filtered image component. | 12-19-2013 |
20130342629 | APPARATUS AND METHOD FOR MODIFICATION OF TELECOMMUNICATION VIDEO CONTENT - A method that incorporates teachings of the subject disclosure may include, for example, utilizing a system including at least one processor for determining a video modification plan for a received video stream of a video call session according to the at least one party associated with the video call session, modifying, by the system, a plurality of background images of the received video stream according to the video modification plan to generate a plurality of modified background images, and generating, by the system, a modified video stream according to the plurality of modified background images. Other embodiments are disclosed. | 12-26-2013 |
20140313277 | SYSTEM AND METHOD FOR PROVIDING SEPARATE COMMUNICATION ZONES IN A LARGE FORMAT VIDEOCONFERENCE - A system that incorporates the subject disclosure performs, for example, displaying a video image of a remote scene at a display surface, wherein the remote scene is remote from the display surface. Overlapping video images are obtained from different vantage points of a local scene observable from the display surface. A composite video image is generated of the local scene from the video images and forwarded to the remote location. A first audio signal is generated representing first sounds associated with a first region of the local scene without representing other sounds associated with a second region of the local scene. The first audio signal is forwarded to audio processing equipment at the remote location to present the first sounds at a first region of the remote scene at the remote location without presenting the first sounds at a second region of the remote scene. Other embodiments are disclosed. | 10-23-2014 |
20150071533 | GUIDED IMAGE UPSAMPLING USING BITMAP TRACING - A method of increasing resolution of an image includes generating vector contours associated with a first image and scaling the vector contours to a second resolution. The first image has a first resolution, and the second resolution is greater than the first resolution. The vector contours are rendered to generate a guiding image at the second resolution, and a second image is generated from the first image based on the guiding image, by using joint upsampling. The second image is generated at the second resolution. The vector contours can be generated by bitmap tracing binary images at different quantization levels. An apparatus and computer readable device implementing the method of increasing the resolution of an image are also provided. | 03-12-2015 |
20150078675 | METHOD AND APPARATUS FOR IMAGE FILTERING - A system that incorporates the subject disclosure may include, for example, partitioning the image into a group of blocks, calculating principle bilateral filtered image components for a first subset of the group of blocks where the principle bilateral filtered image components are not calculated for a second subset of the group of blocks, and applying an infinite impulse response filter to the image using the principle bilateral filtered image components. Other embodiments are disclosed. | 03-19-2015 |
