- 矩阵中的每一个元素称为像元、像素或图像元素。而g(i, j)代表(i, j)点的灰度值，即亮度值。 由于g (i, j)代表该点图像的光强度（亮度），而光是能量的一种形式，故g (i, j)必须大于零，且为有限值，即： 0＜=g (i, j)＜2n。 用g (i, j)的数值来表示(i, j)位置点上灰度级值的大小，即只反映了黑白灰度的关系。 数字化采样一般是按正方形点阵取样的， -each of the matrix elements known as a pixel, pixe

- DFT(Discrete Fourier Transformation)是数字信号分析与处理如图形、语音及图像等领域的重要变换工具，直接计算DFT的计算量与变换区间长度N的平方成正比。当N较大时，因计算量太大，直接用DFT算法进行谱分析和信号的实时处理是不切实际的。快速傅立叶变换(Fast Fourier Transformation，简称FFT)使DFT运算效率提高1～2个数量级。其原因是当N较大时，对DFT进行了基4和基2分解运算。FFT算法除了必需的数据存储器ram和旋转因子rom外，仍
