The most work is followed: 1 a FFTW algorithm is introduced to be used as FFT of image.

将国际上先进的FFTW算法引入到图像的二维fft计算中。

Much of the work that went into FFTW involved maximizing the number of steps a single core could perform without having to transfer the results.

因此，在FFTW中，大部分的工作就是要最小化单个核的执行步骤数量，这样单个核处理时就不需要在内存中进行太多结果的迁移。

The result of the experiment demonstrates that the presented algorithm is about 30% faster than the abroad used public domain FFT package FFTW.

实验结果表明：描述的算法比目前使用最广泛的公共域FFT程序包FFTW快30%左右。
