当权函数是图像灰度的奇函数时，该算法对图像的随机噪声不敏感。
And the algorithm is insensitive to the random noise when the weight function is an odd function of gray of an image.
本文改进的偶函数和奇函数的AFT算法还分别可以用来计算离散余弦变换(DCT)和离散正弦变换(DST)。
The improved AFT algorithms for even and odd functions can also be used for computing discrete cosine transform (DCT) and discrete sine transform (DST), respectively.
