Description: Approximation of discrete cosine transform (DCT)
is useful for reducing its computational complexity without significant
impact on its coding performance. Most of the existing
algorithms for approximation of the DCT target only the DCT of
small transform lengths, and some of them are non-orthogonal.
This paper presents a generalized recursive algorithm to obtain
orthogonal approximation of DCT where an approximate DCT
of length could be derived a pair of DCTs of length
at the cost of additions for input preprocessing.
