摘    要:提出了一种基于距离加权帧内预测的纹理块划分方法。这种帧内预测的方法能很好地描述纹理的方向,可以为方向变换编码和图像检索等应用提供准确的边信息。实验表明,该方法能准确地采用较大的块来描述纹理简单的图像区域,采用较小的块来描述纹理复杂的区域,且很好地反映了预测方向和纹理方向之间的一致性。

关 键 词:纹理块划分  帧内预测  率失真

Abstract:A method of textured block partition based on a distance weighted intra prediction is presented in this paper.Accurate side information can be provided for directional transform image coding,image retrieval,and so on for this method can describe the directions of image texture very well.The experimental results show that the more complex textured areas are partitioned by the more bigger blocks,and the more simpler textured areas are partitioned by the smaller blocks by this method respectively.
Keywords:textured block partition  intra prediction  rate distortion
