Abstract: In one example, a device for coding video data includes a video coder configured to code an intra random access point (IRAP) picture of a partially aligned IRAP access unit of video data, and code data that indicates, when performing random access from the partially aligned IRAP access unit, at least one picture of a video coding layer that is not correctly decodable. When the video coder comprises a video decoder, the video decoder may skip decoding of the pictures that are not correctly decodable, assuming random access has been performed starting from the partially aligned IRAP access unit.

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.

Abstract: We present a method for parallel axial imaging, or z-microscopy, utilizing an array of tilted micro mirrors arranged along the axial direction. Image signals emitted from different axial positions can be orthogonally reflected by the corresponding micro mirrors and spatially separated for parallel detection, essentially converting the more challenging axial imaging to a lateral imaging problem. Each micro mirror also provides optical sectioning capability due to its finite dimension.

Abstract: A method for video coding is described. Signaling of a maximum number of sub-layers for inter-layer prediction is obtained. A sub-layer non-reference picture is also obtained. It is determined whether a value of a temporal identifier of the sub-layer non-reference picture is greater than the maximum number of sub-layers for inter-layer prediction minus 1. The sub-layer non-reference picture is marked as “unused for reference” if the value of the temporal identifier of the sub-layer non-reference picture is greater than the maximum number of sub-layers for inter-layer prediction minus 1. In some cases a sub-layer non-reference picture is also obtained. It is determined whether a value of a temporal identifier of the sub-layer non-reference picture is greater than the maximum number of sub-layers for inter-layer prediction.

The first-viewpoint image data, the second-viewpoint image data, and the time information are transmitted. The first-viewpoint image data is transmitted in a first stream, and the second-viewpoint image data is transmitted in a second stream.

Abstract: A vehicle collects oblique imagery along a nominal heading using rotated camera-groups with optional distortion correcting electronic image sensors that align projected pixel columns or rows with a pre-determined direction on the ground, thereby improving collection quality, efficiency, and/or cost. In a first aspect, the camera-groups are rotated diagonal to the nominal heading. In a second aspect, the distortion correcting electronic image sensors align projected pixel columns or rows with a pre determined direction on the ground. In a third aspect, the distortion correcting electronic image sensors are rotated around the optical axis of the camera. In a fourth aspect, cameras collect images in strips and the strips from different cameras overlap, providing large-baseline, small-time difference stereopsis.
