代码说明:

设计实现了一个自由手写体数字识别系统。文中首先对待识别数字的预处理进行了介绍,包括二值化、噪声处理、图像分割、归一化、细化等图像处理方法;其次,探讨了数字字符特征向量的提取;最后采用了bp神经网络算法,并以MATLAB作为编程工具实现了具有友好的图形用户界面的自由手写体数字识别系统。实验结果表明,本方法具有较高的识别率,并具有较好的抗噪性能。

    This document covers various aspects the Heston model. The structure and topics covered is as follows: Chapter 1 introduces the model and provides theoretical and graphical motivation for its robustness and hence popularity. It also discusses pricing using the Partial Differential Equation and Equivalent Martingale Measure techniques Chapter 2 discusses how the different components of the model can be evaluated computationally and how this can be achieved with different methods. These methods are then compared to each other. Chapter 3 addresses the calibration problem. Different methods are presented as well as practical implementation, results thereof, and comparisons. All the MATLAB code required to implement the model is provided in the appendix
