  • Abstract
    In this paper, we provide an overview of the DCT/DST transform scheme for intra coding in the HEVC standard. A unique feature of this scheme is the use of DST-VII transforms in addition to DCT-II. We further derive factorizations for fast joint computation of DCT-II and DST-VII transforms of several sizes. Simulation results for the DCT/DST scheme in the HM reference software for HEVC are also provided together with a discussion on computational complexity.
