1. this function is for image (width=176, hight=144) only. but you can modify the related value to fit yours. 2. it is used to evaluate the motion vector between the Nth image and N-1th image. 3. it use Three Steps search algorithm. 4. this algorithm finds the closest pixel near the original pixel in three times.(1.

The recognition of noise as a source of annoyance began in antiquity, but therelationship, sometimes subtle, that may exist between noise and money seems to be a development of more recent times. For example, the manager of a large wind tunnel once told one of the authors that in the evening he liked to hear, from the back porch of his home, the steady hum of his machine 2 km away, for to him the hum meant money. However, to his neighbours it meant only annoyance and he eventually had to do without his evening pleasure.

老外写的小波变换的工具箱，基于MATLAB环境；压缩包内有详细的说明和相关Demo，参考价值较高。(Written by foreigners Wavelet Toolbox, MATLAB-based environment compressed packet has detailed instructions and Demo, a high reference value.)

CASCADING OF UPSAMPLER(L) & DOWN SAMPLER(M) : we can change the sampling rate of the signal by a rational factor L/M. M followed by L & L followed by M cannot be interchanged when L and M contain a common integer factor, i.e., M and L have a common integer factor greater than one

应用MATLAB实现傅里叶变换的源代码，有助于更好的学习傅里叶变换。(Achieve Fourier transform of the source code based on MATLAB, contribute to a better learning Fourier transform..)

this is very important matlab code for neural networks...
