用MATLAB写的图像处理，包括绘制直方图，灰度拉伸，图像均衡化及频域平滑滤波代码，简洁实用，注释清晰(Written using MATLAB image processing, including the plot histogram, gray stretch, image equalization and frequency domain filtering code, simple and practical, clear notes)

基于高斯线性的概率密度函数滤波估计，以此为蓝本有很多改进或类似的算法，比如CDKF-PHD等(Based on Gaussian probability density function of the linear filter estimation, there are a lot of improvements as a blueprint or similar algorithms, such CDKF-PHD, etc.)

Communition MATLAB (Proakis)书的源程序，很不错(Communition MATLAB (Proakis) source book, very good)
