摘要
为探索新的数字图像处理方法，研究了数字图像的频谱，特别研究了幅值谱对图像的影响。从高频和低频两个角度，分别研究了频谱。以一幅图像为例，通过Mat Lab进行仿真和分析。尤其是对幅值谱的理论研究，为实现新的数字图像处理方法奠定了基础。
In order to find new method of digital image processing, frequency spectrum is researched in the paper. Especially, research the effect of amplitude spectrum. The research includes high-frequency study and low-frequency study. In addition, MatLab simulation is given. The study of amplitude spectrum is especially important, which is the base of further research for digital image processing.
