摘要： A camera system acquires multiple optical characteristics at multiple resolutions of a scene. The camera system includes multiple optical elements arranged as a tree having a multiple of nodes connected by edges. the nodes represent optical elements sharing a single optical center, and the edges representing light paths between the nodes. The tree has the following structure: a single root node acquiring a plenoptic field originating from a scene; nodes with a single child node represent filters, lenses, apertures, and shutters; nodes with multiple child nodes represent beam splitters and leaf nodes represent imaging sensors. Furthermore, a length of the light paths from the roof node to each leaf nodes can be equal.

摘要： A method models a three-dimensional object with a compressed surface reflectance field. Images of the object are acquired with multiple cameras for multiple viewpoints under different lighting conditions. The images are stored in a matrix Mr representing a surface reflectance field for the three-dimensional object. The matrix Mr is factorized into principle components pck and coefficients cfk. The principal components pck are stored in a matrix Mpc. The matrix Mpc is then factorized into principle components pcm and coefficients cfk which can be stored for each vertex V of a model of the three-dimensional object. The corresponding values of the principle components pcm, coefficients cfk, and coefficients cfk, respectively represent a compression of a surface map, which can be rendered from arbitrary viewpoints and under arbitrary lighting conditions.

摘要： A wide spread adoption of 3D videos and technologies is hindered by the lack of high-quality 3D content. One promising solution to address this problem is to use automated 2D-to-3D conversion. However, current conversion methods, while general, produce low-quality results with artefacts that are not acceptable to many viewers. Creating a database of 3D stereoscopic videos with accurate depth is, however, very difficult. Computer generated content can be used to generate high-quality 3D video reference database for 2D-to-3D conversion. The method transfers depth information from frames in the 3D reference database to the target frame while respecting object boundaries. It computes depth maps from the depth gradients, and outputs a stereoscopic video.

摘要： A method for creating a replication material corresponding to the appearance of a translucent or partially translucent target material. The appearance of the target material can be measured or may be prescribed by a user. The method includes receiving by a processor optical data related to a target subsurface scattering parameter of the target material. Once the processor has received the optical or light characteristic data, the method includes determining by the processor a replication pigment concentration to replicate the appearance of the target material caused by the target subsurface scattering parameter. The processor determines this concentration based on a plurality of pigment subsurface scattering parameters corresponding to a plurality of stored pigment concentrations in the computing device. Once the replication pigment concentration has been determined, the method includes creating, physically or virtually, the replication material by combining the pigment concentration with a base material.

摘要： Various embodiments of a system and methods for real-time image collection and sharing are described. A group of geographically co-located mobile device users may capture images on the mobile devices during a session. The devices may send the images, during the same session, to a database where the images may be stored as a real-time image collection. The image collection may be shared, during the same session, among the mobile device users. The users may receive notification of new images in the image collection based on user preferences. The users may request, from the image collection, images containing particular content by identifying the content on an image and sending a search request which includes the identified content. A computation server may maintain a data set which associates similar images in the image collection. The data set may be updated for each new image that is added to the image collection.

摘要： A three-dimensional relief can be produced from one or more two-dimensional digital (2D) images. A height field is computed from the 2D images and illumination direction information. The height field comprises a multiplicity of geometric surface elements arrayed in a 2D field corresponding to the pixels of the one or more 2D images. Each geometric surface element corresponds to a pixel of each of the digital images and has at least one height parameter representing a displacement from a surface floor. Once the height field is computed, optimizations can be made to the height field including adding and adjusting albedo and glossy surface finishing. The height field can be used to fabricate relief elements in a material, such that each relief element corresponds in shape, position in the height field, and height above the surface floor, to one of the geometric surface elements in the height field.

摘要： A computer-implemented method that includes segmenting a training image into training image patches, where each training image patch is represented by a linear combination of dictionary image patches from an image dictionary, and each dictionary image patch has a sparse representation coefficient. The method includes segmenting a stylized training image into stylized training image patches, where each stylized training image patch is represented by a linear combination of stylized dictionary image patches from a stylized image dictionary, and each stylized dictionary image patch has a sparse representation coefficient. The method also includes training the image dictionary with the training image patches and the stylized image dictionary with the stylized training image patches in a substantially simultaneous manner. The sparse representation coefficient for each training image patch is substantially similar to the sparse representation coefficient for the corresponding stylized training image patch.

摘要： A computer-implemented method is provided for physical face cloning to generate a synthetic skin. Rather than attempt to reproduce the mechanical properties of biological tissue, an output-oriented approach is utilized that models the synthetic skin as an elastic material with isotropic and homogeneous properties (e.g., silicone rubber). The method includes capturing a plurality of expressive poses from a human subject and generating a computational model based on one or more material parameters of a material. In one embodiment, the computational model is a compressible neo-Hookean material model configured to simulate deformation behavior of the synthetic skin. The method further includes optimizing a shape geometry of the synthetic skin based on the computational model and the captured expressive poses. An optimization process is provided that varies the thickness of the synthetic skin based on a minimization of an elastic energy with respect to rest state positions of the synthetic skin.
