Open publisher page 2 citations

Abstract

The authors present an algorithm for computing updated transform coefficients for the discrete cosine transform-II (DCT-II), discrete sine transform-II (DST-II), discrete cosine transform-IV (DCT-IV), and discrete sine transform-IV (DST-IV). This algorithm is computationally attractive for real-time implementation.>
