A Discrete Tchebichef Transform Approximation for Image and Video Coding

A low-complexity approximation for the 8-point DTT was proposed. The arithmetic cost of the proposed approximation are significantly low, when compared with the exact DTT. At the same time, the proposed tool is very close to the DTT in terms of image coding for a wide range of compression rates.
