Low-complexity Image and Video Coding Based on an Approximate Discrete Tchebichef Transform
P. A. M. Oliveira, R. J. Cintra, F. M. Bayer +3
The usage of linear transformations has great relevance for data decorrelation applications, like image and video compression. In that sense, the discrete Tchebichef transform (DTT…

A Discrete Tchebichef Transform Approximation for Image and Video Coding
P. A. M. Oliveira, R. J. Cintra, F. M. Bayer +2
In this paper, we introduce a low-complexity approximation for the discrete Tchebichef transform (DTT). The proposed forward and inverse transforms are multiplication-free and requ…
