DCT Approximations Based on Chen's Factorization
C. J. Tablada, T. L. T. da Silveira, R. J. Cintra +1
In this paper, two 8-point multiplication-free DCT approximations based on the Chen's factorization are proposed and their fast algorithms are also derived. Both transformations ar…

A Class of DCT Approximations Based on the Feig-Winograd Algorithm
C. J. Tablada, F. M. Bayer, R. J. Cintra
A new class of matrices based on a parametrization of the Feig-Winograd factorization of 8-point DCT is proposed. Such parametrization induces a matrix subspace, which unifies a nu…

Low-complexity 8-point DCT Approximations Based on Integer Functions
R. J. Cintra, F. M. Bayer, C. J. Tablada
In this paper, we propose a collection of approximations for the 8-point discrete cosine transform (DCT) based on integer functions. Approximations could be systematically obtained…
