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 system captures motion data in natural environments. A set of sources and a set of sensors are arranged on an object such as a human body. Each source emits ultrasonic signals detected by the sensors. A driver module is also arranged on the body. The driver module generates the ultrasonic signals for the set of sources and timing signals for the set of sensors. Distances between the set of sources and the set of sensors are measured based on a time of flight of the ultrasonic signals. Three dimensional locations of the set of sources and the set of sensors are determined from the distances. The distance measurements are refined using inertial components that provide rotation rates and accelerations. All these measurements together yield poses or configurations of the object.

摘要： A method extracts an alpha matte from a video acquired of a scene. A set of pinhole or narrow aperture images IP is acquired of the scene with a camera aperture set to a relatively large depth-of-field. The scene includes a background B and a foreground F. A corresponding set of wide aperture images IF is acquired of the scene with the camera aperture set to a relatively small depth-of-field. The respective pinhole and wide aperture images are combined to extract an alpha matte according to α=1+(IF−IP)/(B−BF).

摘要： A method and system acquire and display light fields. A continuous light field is reconstructed from input samples of an input light field of a 3D scene acquired by cameras according to an acquisition parameterization. The continuous light is reparameterized according to a display parameterization and then prefiltering and sampled to produce output samples having the display parametrization. The output samples are displayed as an output light field using a 3D display device. The reconstruction can be performed by interpolating the input samples having the different views;

摘要： A method models a three-dimensional object by first acquiring alpha mattes of the object for multiple viewpoints. The alpha mattes are then projected onto a surface hull completely enclosing the object to construct an opacity hull storing opacity values of the surface of the object. The object is illuminated for various lighting conditions while images are acquired. The images are projected onto the opacity hull to render the object under arbitrary lighting conditions for arbitrary viewpoints.

摘要： A system digitizes a three-dimensional object as a three-dimension model by placing the object on a turntable while taking two sets of corresponding images. The first set of images and the second set of images are obtained while rotating the turntable to a various positions and illuminated the object with the overhead lights and backlights. There is a one to one correspondence for images in each set for each position of the turntable. Object shape data and texture data are respectively extracted from the first and second set of images. The object shape data is correlated with the object texture data to construct the three-dimensional digital model stored in a memory of a computer system.

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： Techniques are described for designing and manufacturing a surface that produces a desired image when illuminated by a light source. As described, the desired image may be decomposed into a collection of Gaussian kernels (referred to as Gaussians). A shape of a micropatch lens corresponding to each Gaussian may be determined, and the resulting micropatch lenses may be assembled to form a highly continuous surface that will cast an approximation of the desired image formed form the sum of a plurality of Gaussian caustics. The disclosed techniques may be used to create a design for a light-redirecting surface amenable to milling (or other manufacturing process).
