语音信号的干扰去除.对原始信号进行频谱分析，确定干扰的频率；根据干扰的特点采用不同的滤波器对信号进行处理(Remove the interference of speech signals. On the original signal spectrum analysis to determine the frequency interference according to the characteristics of interference filters with different signal processing)

Desired beamformer， Beam patterns for broadband array(Desired beamformer, Beam patterns for broadband array)

matlab小程序，用来求趋势，很简单。主要是二次函数拟合趋势。(matlab small program used to find trends, very simple. The main trend is to fit a quadratic function.)

This code is useful for PLD measurement

this is a code to calculate the moment invariant of images. the values which come out are capable of removing rotational, scaling, transnational variation in image given as input.classification can be done with the help of it.
