摘要： A technology is described for performing structure from motion for unordered images of a scene with multiple object instances. An example method can include obtaining a pairwise match graph using interest point detection for obtaining interest points in images of the scene to identify pairwise image matches using the interest points. Multiple metric two-view and three-view partial reconstructions can be estimated by performing independent structure from motion computation on a plurality of match-pairs and match-triplets selected from the pairwise match graph. Pairwise image matches can be classified into correct matches and erroneous matches using expectation maximization to generate geometrically consistent match labeling hypotheses and a scoring function to evaluate the match labeling hypotheses. A structure from motion computation can then be performed on the subset of match pairs which have been inferred as correct.

摘要： An “Oblique Image Stitcher” provides a technique for constructing a photorealistic oblique view from a set of input images representing a series of partially overlapping views of a scene. The Oblique Image Stitcher first projects each input image onto a geometric proxy of the scene and renders the images from a desired viewpoint. Once the images have been projected onto the geometric proxy, the rendered images are evaluated to identify optimum seams along which the various images are to be blended. Once the optimum seams are selected, the images are remapped relative to those seams by leaving the mapping unchanged at the seams and interpolating a smooth mapping between the seams. The remapped images are then composited to construct the final mosaiced oblique view of the scene. The result is a mosaic image constructed by warping the input images in a photorealistic manner which agrees at seams between images.

摘要： A “Finite Element Preconditioner” provides locally adapted hierarchical basis functions for preconditioning large data optimization problems. For example, a few of the many typical graphics applications that make use of iterative optimization solutions include tone mapping, gradient domain blending, colorization, and scattered data interpolation. Preconditioning image data for such optimization problems allows those image optimization problems to be solved using less computational overhead and therefore to produce better quality image outputs with less computational overhead. The Finite Element Preconditioner evaluates data, such as image data, to adapt hierarchical basis functions to inhomogeneous problems for preconditioning large optimization problems. Specifically, the Finite Element Preconditioner evaluates the local structure of a coefficient matrix derived from the data and performs a recursive set of variable eliminations, combined with a simplification of the resulting coarse level problems to obtain bases better suited for problems with inhomogeneous (spatially varying) data, smoothness, and boundary constraints.

摘要： A system and process for generating a panoramic video. Essentially, the panoramic video is created by first acquiring multiple videos of the scene being depicted. Preferably, these videos collectively depict a full 360 degree view of the surrounding scene and are captured using a multiple camera rig. The acquisition phase also includes a calibration procedure that provides information about the camera rig used to capture the videos that is used in the next phase for creating the panoramic video. This next phase, which is referred to as the authoring phase, involves mosaicing or stitching individual frames of the videos, which were captured at approximately the same moment in time, to form each frame of the panoramic video. A series of texture maps are then constructed for each frame of the panoramic video. Each texture map coincides with a portion of a prescribed environment model of the scene. The texture map representations of each frame of the panoramic video are encoded so as to facilitate their transfer and viewing. This can include compressing the panoramic video frames Such a procedure is useful in applications where the panoramic video is to be transferred over a network, such as the Internet.

摘要： A system and process for compressing and decompressing multiple video streams depicting substantially the same dynamic scene from different viewpoints. Each frame in each contemporaneous set of video frames of the multiple streams is represented by at least a two layers—a main layer and a boundary layer. Compression of the main layers involves first designating one or more of these layers in each set of contemporaneous frames as keyframes. For each set of contemporaneous frames in time sequence order, the main layer of each keyframe is compressed using an inter-frame compression technique. In addition, the main layer of each non-keyframe within the frame set under consideration is compressed using a spatial prediction compression technique. Finally, the boundary layers of each frame in the current frame set are each compressed using an intra-frame compression technique. Decompression is generally the reverse of the compression process.

摘要： The claimed subject matter relates to an architecture that can facilitate advertising models in connection with pyramidal volumes of advertising space. In particular, a pixel at one plane of view of an image can be associated with four pixels at a lower plane of view and so on. Advertising rights with respect to the pixel can be offered for sale, which can include all, a subset, or a different set of advertising rights with respect to other pixels in the pyramidal volume. The architecture can construct the data for the image dynamically based upon contextual input and the advertising rights as well as image format can be constructed based upon notions of zoning.
