摘要:

为了充分利用H.264新特性带来的冗余信息对视频传输中的错误进行隐藏,提出了一种新的基于Intra帧的差错隐藏方法,根据丢失块周围子块的预测模式推断出丢失块中各子块的预测模式,再根据推断的预测模式重建丢失块. 试验表明,这种方法能很好地预测出丢失块的预测模式,并能适应不同内容类型的图像,差错隐藏的效果明显.

Abstract:

Some new features are introduced in H.264, such as variable-size block motion compensation, prediction in Intra-coded frame etc. A novel error concealment method based on Intra-coded frame was proposed it uses the prediction mode of the surrounding sub-blocks to infer the prediction mode of the missing block. The missing block was reconstructed with the inferred prediction mode. Experiments show that the prediction mode of the missing block can be well recovered with the proposed method and good results can be achieved in images of various content types.

Key words: H.264 recommendation, error concealment, Intra prediction
