Fast DCT algorithm with fewer multiplication stages
Yeonsik Jeong, Imgeun Lee, Kim, Kyu Tae Park · Electronics Letters · 1998
A novel fast DCT scheme with reduced multiplication stages and fewer additions and multiplications is proposed. The proposed algorithm is structured so that most multiplications tend to be performed at the final stage, which reduces the propagation error that could occur in the fixed-point computation. Minimisation of the multiplication stages can further decrease the error.
