FFTmatlab
- 做FFT只能看出信号在0到分析频率(采样频率的一半)之间的相对分布,或者说得到以采样频率归一化的频率。 采样频率即取样频率,指每秒钟取得信号样本的次数。所以,采样频率就是1/(delta t),其中delta t为连续采两次信号的时间间隔。 采样频率/采样点数=频率分辨率。 -Signal do FFT can only be seen in the 0 to the analysis frequency (half the sampling frequency) relative
二维小波变换
- 关于二维小波变换的程序 [精华] 说明:此算法重在概念,速度并不是很快。因为FOR循环的缘故。此程序从循环矩阵的观点出发,把圆周卷积和快速幅里叶变换建立了联系。实现了分解和无失真重构。它只做了一层分解,即将256x256图形分解成为64x64的四个图形,避免了使用WKEEP()的困惑。主要思想为用小波滤波器族构造正交阵W,变换写为B=W*A*W ,反变换为:A=W *A*W,这与所有正交变换无异。W为循环正交矩阵,因此可用FFT实现快速运算,难点就在重构矩阵上。若用矩阵概念明确,一个
