In this paper, the fast one-dimensional (1-D) 8times8 integer transforms and the sharing design for 1-D 8 times 8 forward and inverse integer transforms of H.264/AVC are proposed by using the matrix operations, which are the row/column permutations, the decompositions with the sparse matrices, and the matrix offset computations. The computational complexities of the proposed fast 1-D 8times8 forward...
In this letter, the fast one-dimensional (1-D) algorithms and their sharing design for 1-D inverse integer transforms of H.264/AVC and VC-1 are proposed by using the matrix decompositions with the sparse matrices and the matrix offset computations. The computational complexities of the proposed fast 1-D 4 times 4 and 8 times 8 inverse integer transforms for H.264/AVC are the same as those of the previous...
