摘要： Image resizing for web-based searching is described. In one implementation, a system resizes a user-selected thumbnail image into a larger version of the image that emulates the quality of a large, original image, but without downloading the original image. First, the system extracts resizing parameters when each thumbnail image is created. Then, the system creates a codebook of primitive visual elements extracted from a collection of training images. The primitive visual elements in the codebook provide universal visual parts for reconstructing images. The codebook and a resizing plug-in can be sent once to the user over a background channel. When the user selects a thumbnail image for enlargement, the system resizes the thumbnail image via interpolation and then refines the enlarged image with primitive visual elements from the codebook. The refinement creates an enlarged image that emulates the quality of the large, original image, without downloading the original image.

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： 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.
