摘要
为了更有效地计算二维离散余弦变换──DCT,提出了一种直接作用于二维数据集的快速算法,分析了该算法的运界特点.用Turboc2.0实现了一个8×8数字图象像素块DCT变换与IDCT变换,并对仿真结果进行了分析.
In order to compute two-dimensional Diserete Cosine Transforr-DCT more efficient, in this paper, we present a fast method which work directly to two-dimensional data collections, and we analyze the character of the method, we realize Discrete Cosine Transform and inverse Discrete Cosine Transform of 8×8 digital image element square's using computer simulate. And we analyze the imageable simulate result.
