摘要： A camera aperture includes a first polarizer and a second polarizer with a polarization 90° with respect to the first polarizer. The second polarizer has a through hole at a center. A polarizing rotator is disposed between the first polarizer and the second polarizer. A size of the aperture is changed when a voltage is applied selectively to the polarizing rotator.

摘要： The disclosure provides a technique for recursively partitioning a 3D model of an object into two or more components such that each component fits within a predefined printing volume. The technique includes determining a set of planar cuts each of which partitions the 3D model into at least two components, evaluating one or more objective functions for each cut in the set of planar cuts, and selecting a cut from the set of planar cuts based on the evaluations of the objective functions. In addition, the technique includes, upon determining that a component resulting from the selected cut does not fit within the predefined printing volume, further partitioning that component.

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.

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 one or more 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 or adjustments can optionally be made to the height field. 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 method for generating a self-occlusion surface for an image. The method includes receiving the image, receiving a selection of a material with which to construct the self-occlusion surface, and receiving calibration data associated with the material.

摘要： A computer implemented method tracks 3D positions of an object moving in a scene. A sequence of images is acquired of the scene with a set of cameras such that each time instant a set of images are acquired of the scene, in which each image includes pixels. Each set of images is aggregated into a synthetic aperture image including the pixels, and the pixels in each the set of images are matched corresponding to multiple locations and multiple depths of a target window with an appearance model to determine scores for the multiple locations and multiple depths. A particular location and a particular depth having a maximal score is selected as the 3D position of the moving object.

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.
