GA_SVM
对于小样本而言,SVM的仿真效果要比神经网络好,但是SVM的性能依赖于它的两个训练参数,本算法是用GA自动选择SVM的两个参数。(For small sample case, SVM simulation results than the neural network is good, but the performance of SVM depends on its two training parameters, the algorithm is automatically selected GA parameters of SVM-2.)

brownianbridge
An example case is considered to price an option at a maturity of T years - prices are simulated for Geometric brownian motion process at 2*T maturity, and Brownian Bridge is used to obtain prices at T maturity. Finally option prices are compared to Black Scholes values to verify results(An example case is considered to price an option at a maturity of T years- prices are simulated for Geometric brownian motion process at 2*T maturity, and Brownian Bridge is used to obtain prices at T maturity.

用matlab编程工具,编写具有操作界面的应用程序,通过菜单、对话框,选项框等界面控制,对算法进行演示。需要在应用系统中实现的算法及功能包括:
1、图像增强算法
(1)灰度线形变换:亮度及对比度可以调节(通过控制参数的改变,能够实时预览变化结果);
(2)直方图均衡:可在界面上对比均衡前后的效果。
2、图像变换算法
(3)对一幅彩色图像进行DCT变换和反变换,对比结果和原图;
(4)仅保留左上角16X16的DCT系数,进行反变换,计算结果图的信噪比SNR。
3、图像分割算法
(5)采用最优阈值算法对灰度图像进行分割;
(6)用Canny算法对灰度图像进行边缘检测;
(7)用hough变换,检测边缘图像中的直线,并用不同颜色将检测出的直线叠加显示到原图像上。
