摘要: Described herein is a technique for creating a 3D face model using images obtained from an inexpensive camera associated with a general-purpose computer. Two still images of the user are captured, and two video sequences. The user is asked to identify five facial features, which are used to calculate a mask and to perform fitting operations. Based on a comparison of the still images, deformation vectors are applied to a neutral face model to create the 3D model. The video sequences are used to create a texture map. The process of creating the texture map references the previously obtained 3D model to determine poses of the sequential video images.

摘要: Shadows, which play an important role in perceiving the shape and texture of an object, are simulated interactively in a real time, self-shadowing of a bump mapped surface for a computer rendered object. A computer graphics textured object function defines a horizon map over an orientation in a tangent space of the object using different textures or basis functions. The implementation can be performed using commodity graphics hardware by precomputing the horizon map for limited visibility for each point on the bump mapped surface given light in each of a plurality of radial directions. The horizon map is used to produce self-shadowing of the bump mapped surface of the object.

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: Various embodiments provide techniques for scrubbing variable paths in content. By way of example and not limitation, scrubbing can include receiving user input that defines a scrub path and navigating a data path through content based on the scrub path. According to some embodiments, a data path can include one or more predefined paths (e.g., a travel route) through the content. One or more of the techniques can account for variations in a data path and provide ways of maintaining adjacency between a scrub path and navigation along the data path. In some embodiments, a data path can be associated with one or more types of data path content that can be presented in response to a navigation of the data path.

摘要: The mobile image viewing technique described herein provides a hands-free interface for viewing large imagery (e.g., 360 degree panoramas, parallax image sequences, and long multi-perspective panoramas) on mobile devices. The technique controls the imagery displayed on a display of a mobile device by movement of the mobile device. The technique uses sensors to track the mobile device's orientation and position, and front facing camera to track the user's viewing distance and viewing angle. The technique adjusts the view of a rendered imagery on the mobile device's display according to the tracked data. In one embodiment the technique can employ a sensor fusion methodology that combines viewer tracking using a front facing camera with gyroscope data from the mobile device to produce a robust signal that defines the viewer's 3D position relative to the display.

摘要: An image may be dehazed using a three-dimensional reference model. In an example embodiment, a device-implemented method for dehazing includes acts of registering, estimating, and producing. An image that includes haze is registered to a reference model. A haze curve is estimated for the image based on a relationship between colors in the image and colors and depths of the reference model. A dehazed image is produced by using the estimated haze curve to reduce the haze of the image.
