摘要： Methods and systems are disclosed for processing image frames to reduce the bandwidth requirements. Embodiment of the present invention may include mode-specific image frame rendering in photorealistic and non-photorealistic modes, such as outline and cartoon modes. In embodiments, update regions may be identified and reduced by an edge position mask. In embodiments, update regions may be bounded by rectangles and such regions may be reduced in number by merging regions together using various no-cost or cost approaches. To improve compressibility, regions to be transmitted that do not require updating at the receiver may be encoded as transparent.

摘要： Disclosed are systems and methods for developing robust features for representing data. In embodiments, a linear generative model is computed using data. In embodiments, based upon a robustness measure, a set of features is selected. In embodiments, the set of features may be evaluated to gauge the capacity of the set of features to represent the data. Responsive to the set of features not satisfying an evaluation criterion or criteria, the set of features may be refined until the selected set of features complies with the evaluation criterion or criteria.

摘要： An image created by a first projector is recreated using a second projector by relating the two projectors to a common point of view, preferably as viewed from a camera. A first transport matrix T1 is captured to relate the first projector to the camera. A second transport matrix T2 is then capture to relate the second projector to the camera. To have a first image p1, as projected by the first projector, reproduced by the second projector, the second projector projects a distorted image defined as (T2−1)(T1)p1. The inverse of T2, as used in this equation is an estimation defined by first creating an intermediate matrix {hacek over (T)} of equal size as T2. If a column in T2 is denoted as Tr and a corresponding column in {hacek over (T)} is denoted as {hacek over (T)}r, then the construction and population of {hacek over (T)} is defined as {hacek over (T)}r=Tr/(∥Tr∥)2, and the inverse of T2 is estimated as the transpose of {hacek over (T)}.

摘要： Application of dual photography is simplified by reducing the number of captured images needed to generate a light transport matrix T of (p×q) projection pixel array from (p×q) images to (p+q) images. Manipulation of the light transport matrix is also simplified by replacing the use of a matrix T with an index associating each projection pixel to only non-zero light transport values. By eliminating the use of zero-valued light transport coefficients, the memory and processing requirements for implementing dual photography are greatly reduced. This dual photography technique is applied to the calibration of projector-camera systems. A second method for calibrating projector-camera systems uses a known projection test pattern and a calibrated camera to associate projected markers on a real image to a captured image. Since the real location of the projected markers are determined by the camera, and the relative location of the markers on the test pattern is also known, the projector may be calibrated using homography techniques.

摘要： A surround visual field that has a characteristic or characteristics that relate to an audio/visual presentation is described. In one embodiment, the surround visual field is projected on an area partially surrounding or surrounding video content being displayed on a device. This surround visual field may be comprised of a plurality of elements that further enhance the visual effect of the content being displayed. For example, one embodiment of the invention provides for elements within the surround visual field to move in relation to motion within the video content being displayed. Other characteristics of the video content may also be supplemented by the surround visual field or the surround visual field may simply be authored to correspond to the content itself.
