公開日期: | 三月-1999 | 卷: | vol.47 | 期: | No.3 | 起(迄)頁: | 904-907 | 來源出版物: | IEEE Trans. on Signal Processing | 摘要: | In this correspondence, an index permutation-based fast two-dimensional discrete cosine transform (2-D DCT) algorithm is presented. It is shown that the N × N 2-D DCT, where N = 2m, can be computed using only N 1-D DCT's and some post additions. Index Terms - Discrete cosine transform, fast algorithms, index permutation. © 1999 IEEE. |
