    摘要: Techniques for setting depth values for invalid measurement regions of depth images are described herein. A computing device may set the depth values based on evaluations of depth values of neighboring pixels and of corresponding pixels from time-adjacent depth images. Alternately or additionally, the computing device may utilize a texture image corresponding to the depth image to identify objects and may set depth values for pixels based on depth values of other pixels belonging to the same object. After setting the depth values, the computing device may normalize the depth values of the pixels. Further, the computing device may generate reduced representations of the depth images based on a depth reference model or a depth error model and may provide the reduced representations to an encoder.

    摘要: A proxy-based thin-client web browsing framework enables cooperative web browsing of multiple devices. The multiple devices may include devices that are not intended for web browsing and have limited or no web browsers and/or user input capabilities. The proxy-based thin client web browsing framework employs a virtual browser at a proxy server to perform all browser-engine logics, and retrieve, render and encode web pages on behalf of the multiple devices. The multiple devices therefore only need to have limited decoding and display capabilities to perform web browsing. The proxy-based thin client web browsing framework further includes a touch controller as a remote controller for a device that has no or limited user texting or manipulating capabilities.

    摘要: A method for compressing a high dynamic range (HDR) texture. A first block of texels of the HDR texture in a red-green-blue (RGB) space may be transformed to a second block of texels in a luminance-chrominance space. The first block may have red values, green values and blue values. The second block may have luminance values and chrominance values. The chrominance values may be based on a sum of the red values, a sum of the green values and a sum of the blue values. The luminance values and the chrominance values may be converted to an 8-bit integer format. The luminance values may be modified to restore a local linearity property to the second block. The second block may be compressed.

    摘要: Techniques describe providing a web page for a proxy-based browser on a mobile device to enhance user experience. A proxy server receives a layout of the web page, extracts web elements from the web page, and captures images of the web elements of the web page. The web elements are incorporated with a background screen image to form a composite screen format to represent a display of the web page. The background screen image is compressed by splitting an encoded frame into fixed-size slices and splitting a previous screen frame into fixed-size slices. The proxy server provides the web page synchronized with the mobile device based on the composite screen format and the compressed background screen image. Furthermore, the proxy server receives input from a user to provide updates to web elements that are dynamic on the web page to be displayed on the screen of the mobile device.

    摘要: Digital images are resized according to a prescribed image scaling factor. An original image is re-sampled according to the scaling factor, resulting in an initial resized image. A probability of text (POT) map is generated for the initial resized image, where the POT map specifies a smoothed POT value for each pixel in the initial resized image. A weighting factor (WF) map is generated which maps each different smoothed POT value to a particular WF value. The WF map is used to calculate an adjusted luminance value for each pixel in the initial resized image, resulting in a final resized image.

    摘要: Textual image coding involves coding textual portions of an image. In an example embodiment, a textual block of an image is decomposed into multiple base colors and an index map, with the index map having index values that each reference a base color so as to represent the textual block. A set of neighbor index values are ascertained for a particular index of the index map. A context that matches the neighbor index values is generated from among multiple contexts. The matching context includes a set of symbols. At least one symbol-to-value mapping is determined based on the matching context and a symbol to which the particular index corresponds. The particular index is remapped to a particular value in accordance with the symbol-to-value mapping and the symbol to which the particular index corresponds.

    摘要: A “Remote Display Generator,” as described herein, provides various techniques for providing high-fidelity displays with highly responsive interactive application experiences to clients across a wide range of network bandwidths for remotely hosted applications. In general, the Remote Display Generator uses a compression-friendly remote display architecture as a core. With this compression architecture, actual screen data from a remote server is read out from the display buffer frame by frame, and then compressed with a unified screen codec. Other technologies, including timer-driven screen update models and adaptive transmission mechanisms, are then integrated with various embodiments of the Remote Display Generator to improve overall user experience by improving display quality and responsiveness to user interaction with remotely hosted applications.
