摘要
傅里叶变换是19世纪数学界重要的科研成果,它的处理手段至今为止仍被信号处理领域广泛使用,是线性系统分析方法中最为有利的工具,使人们能够定量地分析数字处理领域中的绝大多数问题,诸如采样点、电子放大器、卷积、滤波、噪声等的作用。在图像处理领域中,将傅里叶变换理论与图像的数字处理理论相结合对于解决大多数图像处理问题都很有帮助。
Fourier transform is one of the most brilliant achievements of mathematical and engineering of nineteenth Century. It has been in the field of signal processing, and is the best means of linear system analysis. It is a favorable tool for analysis of linear system, it enables people to quantitative analysis of digital system, such as sampling, electronic am- plifier, convolution, f＇dtering, noise, such as the role of display point. The Fourier transform theory and its physical inter- pretation of the combination will greatly contribute to the solution of most image processing problems.
