摘要: In this paper, the one-dimensional (1-D) fast 8 x 8 inverse integer transform algorithm for Windows Media Video 9 (WMV-9/VC-1) is proposed. Based on the symmetric property of the integer transform matrix and the matrix operations, which denote the row/column permutations and the matrix decompositions, the efficient fast 1-D 8 x 8 inverse integer transform is developed. Therefore, the computational complexities of the proposed fast inverse transform are smaller than those of the direct method and the previous fast method. With low complexity, the proposed fast algorithm is suitable to accelerate the video coding computations.
