实现图像的傅里叶高通、低通滤波.经Fourier变换后的图像，中间部分是低频部分，外边是图像的高频部分。经过低通滤波后，图像中的高频成分被滤除掉，只留下低频成分，图像的边缘部分变得比较模糊了(useful for image Fourier high-pass, low pass filter)

PCM clustering algorithm

dtw改进算法源码 在matlab下试验 可以很好识别语音(dtw source under test can be very good at matlab voice recognition)

说明：  this is a MT-1D forward modeling code!

The Haar transform can be expressed in the matrix form as T = HIHT (inverse transform HTTH) where I is an NxN image matrix, H is an NxN transformation matrix and T is the resulting NxN transform. For Haar transform, the transformation matrix H contains the Haar basis functions hk(x). They are defined on a continuous, closed interval, x -[0, 1] for k = 0,1,2 ...,N -1 where N = 2n.( The Haar transform can be expressed in the matrix form as T = HIHT (inverse transform HTTH) where I is an NxN image matrix, H is an NxN transformation matrix and T is the resulting NxN transform.
