通过组合两幅图像之间的这些函数并观察第二次变换后的重建图像，分析了傅里叶变换的幅度和相位的重要性。 已经通过考虑几种可能性来研究这种处理，特别是对于结构非常不同的图像。 事实证明，相位携带了最相关的信息，但当普通图像与由强烈标记的几何形式构成的图像组合时，相位就不那么明显了，幅度可以发挥更重要的作用。
The analysis of the importance of the amplitude and the phase of Fourier transform has been carried out by means of combining these functions between two images and observing the reconstructed image after a second transform. This processing has been studied by taking into account several possibilities, especially for very structurally different images. It is proved that the phase carries the most relevant information, but when common images are combined with images constituted by strongly marked geometric forms it is not so evident and the amplitude could play a more important role.
