张正有的相机标定方法，有图片和程序，希望对相机标定的朋友有帮助(Zhang is some camera calibration method, there are pictures and procedures in the hope of the camera calibration of friends to help)

说明：  用MATLAB的神经网络工具箱实现三层BP网络(Using MATLAB)

可以直接计算信号的四阶累计量，挺不错的小程序，注意信号必须是非高斯信号哟。(Signals can be directly calculated fourth-order cumulant, very good small procedures, the attention signal must be a non-Gaussian signal yo.)

这是介绍人工智能中描述逻辑的经典参考书，简要易懂。(This is to introduce artificial intelligence in the classic description logic reference, a brief and understandable.)

高频系数融合均采用基于像素点绝对值取大的规则，这里要注意的是，比较的对象是两幅原始图像的像素点的绝对值，而融合后图像的像素点的取值是两幅原始图像像素点绝对值大的那一点的值，也就是说，要取绝对值大的那个点的实际值

子空间拟合类算法WSF的一种改进算法MVP，用于DOA估计。(Subspace fitting-like algorithm WSF An improved algorithm for MVP, for the DOA estimation.)

A simple example showing how to track an object with particle filter. Likelihood is based on Bhattacharya distance of color histogram.

Matlab code that has function of writting an array of numbers in dat file as hexidecimal numbers that are suited for ADSP-2181.

Bayesian Multi Layer Perceptron Neural Network

这个是对各种信道，如awgn、rayleigh、rice等的一个仿真。简单易懂，意义较大(This is a variety of channels, such as awgn, rayleigh, rice, etc. a simulation. Easy to understand, the larger significance)
