Abstract
This paper extends the theory of multi-dimensional vector orthogonal transformation matrix and presents a new 4D order-4 DCT integer transform operator based on the theory of multi-dimensional vector matrix discrete cosine transform (MD-VMDCT). Meanwhile, the orthogonality of the operator and energy concentration is verified in the paper. Also the comparison between the integer and the float 4D-VMDCT is carried out. At last, the video sequence is compressed using our approach. The experimental results show that the algorithm is correct and effective. It is better than H.264/AVC under the same conditions and it is slightly lower in performance compared with float 4D-VMDCT.
