Abstract: In this paper, we present a discussion on DCT algorithms based on convolutions. It is shown that these approaches can provide effective solutions to realize DCTs. Besides, they provide a theoretical lower bound on the number of multiplications required for the realization of DCTs. Some fast short length DCT algorithms have also been derived from these approaches.
