数字减影(DSA:Digital Subtract Angiography)是一种传统的血管可视化技术[1]。这一技术用注射造影剂后的活动图像减去注射造影剂前记录的掩模图像来显示不透明的血管。其期望的结果是在减影后的图像上背景结构被完全消除。(estimation based on background)

说明：  两种对二阶系统进行参数辨识的最小二乘算法，一种可以直接得到输入输出之间的传递函数，一种可以解出线性的差分方程各系数，再反解得到传递函数。附带的一个二阶系统的模型，可以自行下载导入输入输出数据进行试验。(Two kinds of least square algorithm for parameter identification of second-order system, one can directly get the transfer function between input and output, the other can solve the coefficients of linear difference equation, and then get the transfer function by inverse solution. The attached model of a second-order system can download the input and output data for test.)

在matlab环境下，变程实现了用全局直方图均衡化对图像做反差改善(In matlab environment, the change process to achieve the overall situation with the image histogram equalization contrast to do to improve)

DS_CDMA通信系统的MATLAB仿真源程序，包含发射信号、QPSK调制、GLOD码扩频、解扩、解调等过程(DS_CDMA communication system simulation source of MATLAB, including emission signal, QPSK modulation, GLOD code spread-spectrum despreading, demodulation, etc. )

常用的数据挖掘算法之一，模拟退火算法，Simulated Annealing。(SimulatedAnnealing)

code for averaging,ORing,ANDing images

使用matlab来实现数据的频谱分析，excel数据可以使用随机数据。(Using Matlab to realize signal spectrum analysis, excel can use random data.)

用0.618法和fibonacci法求解单变量的最优化问题，fibonacci法有两个，可以对比，一个慢一个快(With 0.618 Fibonacci method and single-variable optimization problems, fibonacci law there are two, you can contrast a slow one fast)
