    摘要: Dual-mode compression of images/videos for reliable real-time transmission includes a scalable block-based video compression. The method provides graceful quality degradations in case of channel bandwidth changes. Prediction for encoding is avoided, and the process is less complex with less memory requirements. The method involves processing each block independently with the advantage that errors are not able to propagate beyond current block boundaries. Two different encoding modes are used, natural image coding for acquired images and graphics coding for computer generated images. The proper encoding mode is chosen by comparing performance of the two modes for a particular block to be encoded. An embedded bitstream is generated by the encoder in accordance to the available channel bandwidth.

    摘要: A recursive adaptive intra smoothing filter for intra-mode video coding is executed using one or more approaches including, but not limited to matrix multiplication, spatial filtering and frequency domain filtering. Matrix multiplication includes initially computing a prediction matrix Pm using training data. After coding a macroblock, Pm is updated for future macroblocks. In the case of applying spatial filtering, the shift invariance problem is reduced by imposing certain constraints on the matrix to be solved. In frequency domain filtering, a transform residual is minimized using DCT-domain filtering.

    摘要: Compression of graphics images and videos includes partitioning an image into blocks, determining the number of bitplanes for encoding each block, encoding the block by grouping pixel values so that within each group, the pixel values are the same or similar, sending the number of bitplanes, sending the number of groups and the pixel value of each group and sending a signal for each pixel to indicate the group for that pixel, as well as using leftover bits from a bit budget for sending refinement bits for pixels.

    摘要: An improved scalar embedded graphics coding (EGC) for wireless HD compression is described herein. The image frame to be encoded is divided into blocks, which are further divided into color groups. These groups are encoded one bit plane at a time. The improved scalar EGC method and system uses shared grouping data among color components, but bit planes of each color are separately encoded. Further, during encoding a second-level grouping is able to occur on the splitting signaling of the groups. The system and method described herein retain the simplicity of scalar EGC and attain an efficiency comparable to vector EGC.

    摘要: Reordering of a bitstream is able to be used to speed up the decoding in embedded graphics coding. In the reordering, the signaling bits of all of the groups are sent and then the refinement bits of each group follow. With this reordering, the decoder can decode the header, identify the number of refinement bits for each group and locate the starting point of each group within the bitstream, therefore parallel processing of each group is able to be implemented at the decoder side.

    摘要: A method of and system for encoding high definition video content using embedded graphics coding is described. The method determines if the video content includes an RGB or YUV444 color format or a YUV422 color format. If the color scheme includes RGB or YCbCr444 data and separate encoding is used, then all three color components are encoded separately using scalar EGC. If the color scheme includes RGB or YCbCr444 data and joint encoding is used, then all three color components are jointly encoded using joint scalar EGC. If the color scheme includes YCbCr422 data and separate encoding is used, then Y, U and V are encoded separately using scalar EGC. If the color scheme includes YCbCr422 data and joint encoding is used, then Y is encoded by itself using scalar EGC and U and V are jointly encoded using joint scalar EGC.
