摘要： A computer-based method and system for digital 3-dimensional imaging of an object which allows for viewing images of the object from arbitrary vantage points. The system, referred to as the Lumigraph system, collects a complete appearance of either a synthetic or real object (or a scene), stores a representation of the appearance, and uses the representation to render images of the object from any vantage point. The appearance of an object is a collection of light rays that emanate from the object in all directions. The system stores the representation of the appearance as a set of coefficients of a 4-dimensional function, referred to as the Lumigraph function. From the Lumigraph function with these coefficients, the Lumigraph system can generate 2-dimensional images of the object from any vantage point. The Lumigraph system generates an image by evaluating the Lumigraph function to identify the intensity values of light rays that would emanate from the object to form the image. The Lumigraph system then combines these intensity values to form the image.

摘要： Techniques and systems are disclosed for navigating human scale image data using aligned perspective images. A consecutive sequence of digital images is stacked together by aligning consecutive images laterally with an image offset between edges of consecutive images corresponding to a distance between respective view windows of the consecutive images. A view window of an image in the sequence is rendered, where the view window of the image corresponds to a desired location. Offset portions of the view window of a desired number of images in the sequence are rendered, for example, alongside the full view of the image at the desired location.

摘要： A sprite data structure includes multiple pixels that each have conventional image information (e.g., color and transparency) relating to the appearance of the sprite. The data structure of each pixel includes a depth component or value representing a displacement of the pixel from a selected plane. In a sprite rendering process, the depth values of an input or source sprite are forward mapped (i.e., warped) to the depth values of an output or a destination sprite. Based upon the forward mapping of the depth values in the destination sprite, a backward mapping is performed on the image information from the source sprite to the destination sprite so that it can be rendered. This provides the destination sprite with parallax-based offsets that can create a very strong impression of three-dimensionality between and within the sprites.
摘要翻译：子画面数据结构包括多个像素，每个像素具有与子画面的外观相关的常规图像信息（例如，颜色和透明度）。每个像素的数据结构包括表示来自所选平面的像素的位移的深度分量或值。在子画面渲染过程中，输入或源精灵的深度值被前向映射（即扭曲）到输出或目标精灵的深度值。基于目标精灵中的深度值的前向映射，对从源精灵到目标精灵的图像信息执行反向映射，使得可以呈现。这为目标精灵提供了基于视差的偏移，可以在精灵之间和之间产生非常强烈的三维立体感。

摘要： Described is a user interface that displays a representation of a stereo scene, and includes interactive mechanisms for changing parameter values that determine the perceived appearance of that scene. The scene is modeled as if viewed from above, including a representation of a viewer's eyes, a representation of a viewing screen, and an indication simulating what each of the viewer eyes perceives on the viewing screen. Variable parameters may include a vergence parameter, a dolly parameter, a field-of-view parameter, an interocular parameter and a proscenium arch parameter.

摘要： The techniques and mechanisms described herein are directed to a system for stylizing video, such as interactively transforming video to a cartoon-like style. Briefly stated, the techniques include determining a set of volumetric objects within a video, each volumetric object being a segment. Mean shift video segmentation may be used for this step. With that segmentation information, the technique further includes indicating on a limited number of keyframes of the video how segments should be merged into a semantic region. Finally, a contiguous volume is created by interpolating between keyframes by a mean shift constrained interpolation technique to propagate the semantic regions between keyframes.

摘要： A system and method for improving digital flash photographs. The present invention is a technique that significantly improves low-light imaging by giving the end-user all the advantages of flash photography without producing the jarring look. The invention uses an image pair—one taken with flash the other without—to remove noise from the ambient image, sharpen the ambient image using detail from the flash image, correct for color, and remove red-eye.
