20130187846 | BI-ORTHOGONAL PIXEL INTERPOLATION - The techniques described in this disclosure are directed to interpolating pixel values. In some examples, the techniques interpolate a pixel value for an interpolated center pixel based on pixel values of pixel that reside on diagonal lines that are orthogonal to one another. The techniques may determine first order derivative values and, in some examples, second order derivative values to determine which pixels to utilize to interpolate the pixel values for the interpolated center pixel. The techniques may similarly determine pixel values for non-center interpolated pixels using orthogonal vertical and horizontal lines. | 07-25-2013 |
20130251281 | IMAGE ENHANCEMENT - Techniques described in the disclosure are generally related to enhancing portions of an image relative to other portions of the image. The example techniques may utilize depth information in conjunction with one or more viewer perceivable information to enhance portions of the image relative to other portions. The techniques may then display the enhanced image to provide the viewer with a possibly more realistic image. | 09-26-2013 |

20140022339 | CROSSTALK REDUCTION IN MULTIVIEW VIDEO PROCESSING - In one example, a method includes identifying a first set of pixels in co-located pairs in a corresponding pair of multiview image frames for which the co-located pairs have a disparity between the pixels that is greater than a selected disparity threshold. The method further includes identifying a second set of pixels in at least one of the image frames that are within a selected distance of an intensity transition greater than a selected intensity transition threshold. The method further includes applying crosstalk correction to pixels that are identified as being in at least one of the first set and the second set. | 01-23-2014 |
20140022340 | CROSSTALK REDUCTION WITH LOCATION-BASED ADJUSTMENT IN MULTIVIEW VIDEO PROCESSING - In one example, a method includes identifying a pixel in an image frame that is a candidate for causing crosstalk between the image frame and a corresponding image frame in a multiview image system. The method further includes, for a pixel identified as a candidate for causing crosstalk, applying crosstalk correction to the pixel. The method further includes applying a location-based adjustment to the pixel, wherein the location-based adjustment is based at least in part on which of two or more portions of the image frame the pixel is in. | 01-23-2014 |
20140098100 | MULTIVIEW SYNTHESIS AND PROCESSING SYSTEMS AND METHODS - Certain embodiments relate to systems and methods for presenting an autostereoscopic, 3-dimensional image to a user. The system may comprise a view rendering module to generate multi-view autostereoscopic images from a limited number of reference views, enabling users to view the content from different angles without the need of glasses. Some embodiments may employ two or more reference views to generate virtual reference views and provide high quality stereoscopic images. Certain embodiments may use a combination of disparity-based depth map processing, view interpolation and smart blending of virtual views, artifact reduction, depth cluster guided hole filling, and post-processing of synthesized views. | 04-10-2014 |

20140192267 | METHOD AND APPARATUS OF REDUCING RANDOM NOISE IN DIGITAL VIDEO STREAMS - Method and apparatus for reducing random noise in digital video streams are described. In one innovative aspect, the device includes a noise estimator. The device also includes a motion detector configured to determine a motion value indicative of motion between two frames of the video stream, the motion value based at least in part on the noise value. The device further includes a spatial noise reducer configured to filter the image data based at least in part on a blending factor and the noise value. The device also includes a temporal noise reducer configured to filter the video data based on the motion value and the noise value. The device also includes a blender configured to blend the spatial and temporal filtered values to provide a weighted composite filtered output image. | 07-10-2014 |
