Discrete_Cosine_and_Sine_Transforms
继 Discrete Cosine Transform: Algorithms, Advantages, Applications (K. R. Rao and P. Yip) 之后的一本关于离散余弦变换(DCT)的快速实现算法的最新专著. 本书第五章“Integer Discrete Cosine/Sine Transforms”关于DCT整数近似实现写的非常详细和精彩, 很方便大家编程实现. 值得一提的是本书的第一作者Vladimir Britanak 一直在从事DCT, 尤其是改进的离散余弦变换(MDCT)的快速算法的研究.(This book, which is written very carefully, is a new monograph of Discrete Cosine Transform (DCT).The fifth chapter about the Integer Discrete Cosine/Sine Transforms is especially wonderful. )
