Spatial and interlayer hybrid intra-prediction for H.264/SVC video

Spatial and interlayer hybrid intra- prediction for H.264/SVC video

Spatial prediction based intra-coding

According to H.264 video coding standard, spatial prediction is used for intra block coding. The luma prediction may be based on 4×4 block, for which there are nine prediction modes, or 16×16 macroblock., for which four prediction modes. For chroma prediction, there are also four prediction modes. In this paper, a new method is proposed for improving the intra prediction algorithm, the first st...

Regression-based Intra-prediction for Image and Video Coding

By utilizing previously known areas in an image, intra-prediction techniques can find a good estimate of the current block. This allows the encoder to store only the error between the original block and the generated estimate, thus leading to an improvement in coding efficiency. Standards such as AVC and HEVC describe expert-designed prediction modes operating in certain angular orientations al...

Multiple Line-based Intra Prediction for High Efficiency Video Coding

Traditional intra prediction usually utilizes the nearest reference line to generate the predicted block when considering strong spatial correlation. However, this kind of single line-based method does not always work well due to at least two issues. One is the incoherence caused by the signal noise or the texture of other object, where this texture deviates from the inherent texture of the cur...

Fast H.264 intra prediction for network video processing

This letter proposes a fast parallel and deeply pipelined architecture for realtime H.264 intra 4×4 prediction capable of handling up to 32 High Definition video streams (1920× 1080 @ 30 fps) simultaneously, while offering high flexibility and consuming only a fraction of resources available on modern FPGA’s. The design has been validated on target using a state of the art Altera Stratix IV FPGA.
