Abstract: The present invention provides a unique intra prediction process which improves the efficiency of video coding. H.264/AVC uses reference pixels in a horizontal boundary located immediately above a target block to be predicted and reference pixels in a vertical boundary located immediately left of the target block. In the present invention, at least some of one of an array of horizontal boundary pixels and an array of vertical boundary pixels are retrieved. Then, the retrieved pixels are added to the other boundary pixels to extend the array thereof. Intra prediction is performed, based solely on the extended array of boundary pixels.

Abstract: A method of balancing colors of three-dimensional (3D) points measured by a scanner from a first location and a second location. The scanner measures 3D coordinates and colors of first object points from a first location and second object points from a second location. The scene is divided into local neighborhoods, each containing at least a first object point and a second object point. An adapted second color is determined for each second object point based at least in part on the colors of first object points in the local neighborhood.

Abstract: Methods of encoding and decoding for video data are described for encoding or decoding multi-level significance maps. Distinct context sets may be used for encoding the significant-coefficient flags in different regions of the transform unit. In a fixed case, the regions are defined by coefficient group borders. In one example, the upper-left coefficient group is a first region and the other coefficient groups are a second region. In a dynamic case, the regions are defined by coefficient group borders, but the encoder and decoder dynamically determine in which region each coefficient group belongs. Coefficient groups may be assigned to one region or another based on, for example, whether their respective significant-coefficient-group flags were inferred or not.

The 3D representations of noteworthy locations may be provided in a database that may be stored local or remote to the imaging device or a programmable device processing images obtained from the imaging device.

Abstract: A cover glass of an electronic device may be inspected for defects and damage such as cracks, fractures, scratches, and chips. The electronic device may be placed in an enclosure with a lighting assembly that emits light to the electronic device, and scattered light from defects and damage of the cover glass is captured by an imaging device. A shutter assembly facilitates the capture of scattered light and reduces the capture of reflected light, which enhances the exposure of defects and damage of the captured image of the cover glass. A mirror facilitates the capture of a side surface of the electronic device.

Abstract: A multiple target tracker and beam steerer utilizes liquid crystal waveguide (LCWG) beam steering to illuminate multiple tracked targets per frame one target at a time for designation, range finding or active imaging. The steering rate and range afforded by the LCWG supports various tracker configurations (out-of-band, in-band or dual-band video cameras), LADAR detectors (single pixel or pixelated) and prioritization of tracked targets to vary the revisit rate or dwell time for an illuminated target. A user interface accepts commands from an operator to select the targeting mode, control cue-box size and position within the FOV and target selection.

Abstract: Blurring is simulated in post-processing for captured images. A 3D image is received from a 3D camera, and depth information in the 3D image is used to determine the relative distances of objects in the image. One object is chosen as the subject of the image, and an additional object in the image is identified. Image blur is applied to the identified additional object based on the distance between the 3D camera and the subject object, the distance between the subject object and the additional object, and a virtual focal length and virtual f-number.

Abstract: In high-dynamic range (HDR) coding, content mapping translates an HDR signal to a signal of lower dynamic range. Coding and prediction in layered coding of HDR signals is improved if content mapping utilizes signal color ranges beyond those defined by a traditional electro-optical transfer function (EOTF) or its inverse (IEOTF or OETF). Extended EOTF and IEOTF functions are derived based on their mirror points. Examples of extended EOTFs are given for ITU BT. 1886 and SMPTE ST 2084.
