    Abstract: A device, system and method for determining a position of a movable object on a two-dimensional surface obtains, via an image capture device attached to the movable object, at least one image of a portion of the two-dimensional surface. At one virtual marker is identified in at least one image, and a previously determined estimated position of the at least one virtual marker is retrieved. The previously determined estimated position determined from a combination of an image of at least one anchor point on the two-dimensional surface, the at least one anchor point defining a unique position on the two-dimensional surface, and odometry measurements based on at least two images of the two-dimensional surface. The position of the movable object on the two-dimensional surface is determined from the estimated position of the at least one virtual marker.

    Abstract: A method for controlling relocation of a session of an application hosted in a first server (220) connected to a radio station (301) configured for communication with wireless devices (303), comprising the steps of running (51) a session of the application between an application host in said server and an application client in a first wireless device; obtaining (53) context data in the server, which context data is related to the first wireless device during said session; providing (55) said context data to a management entity configured to control relocation of said session from the first server to a second server.

    IPC: G06T3/40

    Abstract: Techniques for demosaicing of digital color images are improved by estimating and using the structural instability in the neighborhood of the respective pixel. The structural instability for a color is given by the range of the color values for this color in a first local region around each current pixel. A method is executed by a device for interpolating a missing color at the current pixel in a color image produced by a digital image sensor having a color filter array, the current pixel having a current color that differs from the missing color. The method comprises: computing (51) a range value for one of: pixels having the missing color and pixels having the current color; computing (52) an interpolation value at the current pixel as a function of the range value and color values for pixels having the missing color within a second local region around the current pixel; and setting the missing color at the current pixel to the interpolation value.

    IPC: G06T5/00

    Abstract: A digital color image is processed for correction of lateral chromatic aberration in a current color plane (CCP). The processing identifies (502), within each of a plurality of predetined search regions distributed over the image, selected blocks comprising intensity edge(s) in both CCP and a reference color plane (RCP). The processing further determines (503), for each selected block in CCP, a radial scaling factor that minimizes a measure of difference between the intensity edges in CCP and RCP, and processes (504) the redial scaling factors of the selected blocks to determine a spatial scaling function that relates radial scaling to radial distance from an image reference point. The processing further recalculates (505) color values in CCP by computing an interpolated color value for each image pixel at an updated pixel location given by the spatial scaling function for the respective image pixel. The method may be operated on a mosaiced or a demosaiced image.
