摘要： 将彩色视频表示在四维矩阵的数学模型中，并利用四维矩阵离散余弦变换（4D-MDCT）统一处理彩色视频的多个帧是视频编码算法的一个新思路。该文基于4D-MDCT并结合四维帧内预测技术提出了一种彩色视频编码的新方法。实验结果表明，该方法能够进一步提高基于4D-MDCT的彩色视频压缩编码的性能。

Abstract: It is a novel idea of video coding algorithm that represents color video in the mathematic model of four-dimensional matrix and encodes multiple frames of color video using four-dimensional matrix discrete cosine transform(4D-MDCT). A new color video coding method which combines 4D-MDCT and four dimensional intra prediction is proposed. The experimental results show that the proposed algorithm can improve the performance of color video compression based on 4D-MDCT further.
