加深对卡尔曼滤波算法的理解，了解卡尔曼滤波器算法的基本特点，掌握卡尔曼滤波算法应用研究的基本步骤和方法(deepen the Kalman filter algorithm understanding, knowledge Kalman Filter algorithm for the basic features, master Kalman filtering algorithm applied research on the basic steps and methods)

主要使图像进行灰度化处理，matlab的源代码，视同再进一步的预处理中应用(Gray image)

混合编程方法,便于VC++与matlab进行混合编程(matlab and vc++ mex)

很好用的matlab wavelet,,,,,,,,,,(Good use of the matlab wavelet ,,,,,,,,,,)

基于遗传交叉的粒子群优化算法有很好的计算效果(Genetic cross-PSO has good calculation results)

对接收信号进行转化和功率谱分析。得到信号的统计特性，主要是噪声放面。(The received signal is transformed and the power spectrum analysis. Get the statistics of the signal, is mainly the noise area.)
