Multi-dimensional Vector Matriz DCT Integer Transform for Video Encoding
This paper presents a new integer DCT 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 our experiment. At last the video sequence is compressed by 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 can avoid inverse transform mismatch problems and minimize computational complexity slightly lower in performance compared with float 4D-VMDCT.
