In AVC, 8 directional prediction modes (plus the DC prediction mode) are defined. The prediction mode number is signaled to the decoder using a simple predictive coding method. The previous intra prediction methods have two major disadvantages: lack of precision for arbitrary directional patterns and accuracy lack of accuracy to exploit geometric dependency between blocks. To address these issues, a new method accurately predicts the intra directions from reconstructed neighboring pixels and differentially encode the intra directions.

20130235231 | VECTOR EMBEDDED GRAPHICS CODING - A method of coding High Definition (HD) color pictures is described. The method divides the HD picture into individual bit planes of the three colors. The method then interleaves the bit planes such that bit planes of the three colors having the same significance are coded together. The method codes a block of the picture based on the bit distribution in corresponding groups of the corresponding bit planes of the three colors. The method performs a first level grouping of bits in a bit plane of an image and a second level grouping of the first level grouping bits of different color components within a group. | 09-12-2013 |
20130236097 | EMBEDDED GRAPHICS CODING FOR IMAGES WITH SPARSE HISTOGRAMS - Processes for compressing images with sparse histograms are disclosed. The image is divided into blocks, and a bit budget is assigned for each block. The pixels of a block are converted and coded bit-plane by bit-plane, starting from the Most Significant Bit (MSB) and going towards the Least Significant Bit (LSB). The pixels of the block are partitioned into groups. Each group contains pixels that have same value. Moving from the MSB to the LSB, the groups in each bit-plane are processed. When processing a group, the encoder sends a “0” if all group members have same bit value at the current bit-plane being processed, followed by the bit value; otherwise, the encoder sends a “1”, followed by refinement bits for each pixel of the group, and the encoder splits the group. | 09-12-2013 |
20130246712 | Methods And Apparatuses For Efficient Load Processing Using Buffers - Various embodiments of the invention concern methods and apparatuses for power and time efficient load handling. A compiler may identify producer loads, consumer reuse loads, consumer forwarded loads, and producer/consumer hybrid loads. Based on this identification, performance of the load may be efficiently directed to a load value buffer, store buffer, data cache, or elsewhere. Consequently, accesses to cache are reduced, through direct loading from load value buffers and store buffers, thereby efficiently processing the loads. | 09-19-2013 |

20140314150 | CODEWORD ASSIGNMENT FOR INTRA CHROMA MODE SIGNALING FOR HEVC - Intra prediction is used in state-of-the-art video coding standards such as AVC. The intra prediction modes are coded into the bitstream. Luma and chroma components could potentially have different prediction modes. For chroma components, there are 5 different modes defined in AVC: vertical, horizontal, DC, diagonal down right, and “same as luma”. Statistics show that the “same as luma” mode is frequent used, but in AVC, this mode is encoded using more bits than other modes during entropy coding, therefore the coding efficiency is decreased. Accordingly, a modified binarization/codeword assignment for chroma intra mode signaling is able to be utilized for high efficiency video coding (HEVC), the next generation video coding standard. | 10-23-2014 |
