摘要： Wyner-Ziv and wavelet video coding is described. In one aspect, Wyner-Ziv frames from multiple frames of source video content are zero-tree entropy encoded to generate encoded Wyner-Ziv content. The zero-tree entropy encoding operations are based on high-order statistical correlations among wavelet transforms from the Wyner-Ziv frames. The encoded Wyner-Ziv content is communicated to a decoder for decoding to generate reconstructed Wyner-Ziv frames for presentation to a user.

摘要： An accelerated screen codec technique is described that provides a general screen compression framework, which, in one embodiment, is Graphics Processor Unit (GPU) friendly. In one embodiment, in order to compress screen data, blocks in a compound screen image containing both images and text are segmented into text blocks and pictorial blocks using a simple gradient-based procedure. The text and pictorial blocks are then compressed respectively via different compression techniques. Additionally, a GPU acceleration architecture of one embodiment of the accelerated screen codec technique provides a screen codec that maximally exploits a GPU's high parallelism and reduces the download bandwidth from GPU to Computer Processing Unit (CPU).

摘要： Progressive distributed video coding is described. In one implementation, video data maybe encoded by arranging the data into bit-planes. The arrangement of bit-planes is adapted by shifting the first non-zero bit-plane left by one place in the binary digits and moving the sign bit immediately in the place vacated by the shifted non-zero bit-plane. The adapted bit-planes are then encoded using an asymmetric Slepian-Wolf encoder.

摘要： A method and system for coding a multi-view video having multiple views based on temporal decomposition and view decomposition is provided. A multi-view video coding (“MVC”) system provides a disparity compensated view filter based on a generic lifting transform that is used in conjunction with a motion compensated temporal filtering and a two-dimensional spatial discrete wavelet transform to decompose a multi-view video into four-dimensional wavelet coefficients. The MVC system performs a hierarchy of decompositions for each view that may be a combination of temporal decompositions and view decompositions.

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 Wyner-Ziv coding scheme jointly utilizes multiple side information at the decoder is described. A new probability model is introduced based on an extended turbo decoding trellis, so that the transitional probability is calculated from the probabilities conditioned on multiple side information. The proposed scheme handles multiple side information in a multi-dimensional manner to potentially achieve coding performance better than either selecting one side information or generating a single side information by averaging several side information. When the decoder receives multiple streams of parity bits, the conditional probabilities on the parity bits from the multiple streams all contribute in turbo decoding. The errors existing in some of the streams can be automatically eliminated during the decoding process.
摘要翻译：描述了在解码器处共同利用多边信息的Wyner-Ziv编码方案。基于扩展turbo解码网格引入新的概率模型，从而根据多边信息的概率计算过渡概率。所提出的方案以多维方式处理多个侧面信息，以便比选择一个侧面信息或通过平均多个边缘信息来生成单个侧面信息来潜在地实现编码性能。当解码器接收到多个奇偶校验位流时，来自多个流的奇偶校验位的条件概率在turbo解码中都有贡献。在解码过程中可以自动消除一些流中存在的错误。
