    摘要: A system encodes videos acquired of a moving object in a scene by multiple fixed cameras. Camera calibration data of each camera are first determined. The camera calibration data of each camera are associated with the corresponding video. A segmentation mask for each frame of each video is determined. The segmentation mask identifies only foreground pixels in the frame associated with the object. A shape encoder then encodes the segmentation masks, a position encoder encodes a position of each pixel, and a color encoder encodes a color of each pixel. The encoded data can be combined into a single bitstream and transferred to a decoder. At the decoder, the bitstream is decoded to an output video having an arbitrary user selected viewpoint. A dynamic 3D point model defines a geometry of the moving object. Splat sizes and surface normals used during the rendering can be explicitly determined by the encoder, or explicitly by the decoder.

    摘要: A face is scanned to obtain a three-dimensional geometry of the face, images are also acquired of the face, and subsurface scattering of the face is measured. A translucency map is determined from the subsurface reflectance. A total surface reflectance and a normal map are estimated from the three-dimensional geometry and the images, and diffuse reflectance is estimated using the total reflectance. An albedo map is determined from the diffuse reflectance. The diffuse reflectance is subtracted from the total reflectance to obtain a surface reflectance. A set of bi-directional reflectance functions is fitted to the surface reflectance. Then, the set of bi-directional reflectance distribution functions, the albedo map, and the translucency map are combined to form a skin reflectance model of the face.

    摘要: A method renders a model of an object by first acquiring, in an acquisition space, a reflectance field of the object. The reflectance field includes a set of reflectance images of the object and a point model of the object. The model is deformed in an object space to generate a deformed model. For each point of the deformed model in the object space, the set of the reflectance images is queried in the acquisition space to obtain reflectance coefficients for each point. Each point of the deformed model is then shaded according to the corresponding reflectance coefficients to generate an image of the object reflecting the deforming.

    摘要: A technique for fabricating a highlight hologram based on a digital object performs point sampling on the object and represents each sampled point as a geometric patch. A set of geometric patches corresponding to sampled points from the object are fabricated into a substrate. A paraboloid patch may be used for reflective substrates while a hyperboloid may be used for transmissive substrates. To avoid specifying overlapping patches, which are impractical to fabricate, certain of the sample points may be merged. An output set of grooves is saved and may be used to specify fabrication of a highlight hologram on the physical substrate.
