基于VC 手写数字识别程序设计

1、基于VC 手写数字识别程序设计 ;/计算当前画板中数字的特征值GetTeZheng ;/首先判断当前的数字类型是否已经在模板中for int j 0;j i;j+ cf.Read void * temp,sizeof TEZHENG ;/从文件cf的当前位置读数据for int k 0;k 15;k+ if temp- VHDerectionk! mytezheng- VHDerectionk /判断水平特征break; if k 15 && temp- decon mytezheng- decon && temp- lenfirst mytezheng- le

2、nfirst && temp- lenth1 mytezheng- lenth1 && temp- lenth mytezheng- lenth && temp- lenend mytezheng- lenend char s20;sprintf s,"您输入的是：%d，数据已有",temp- value ;AfxMessageBox s ;break; /说明该数字类型不在模板中if j i if inputdlg.DoModal IDOK /判断数字输入对话框中的两个数字是否相同if inputdlg.m_value1!

3、inputdlg.m_value2 AfxMessageBox "您的输入有误，n请重新输入" ; /相同，则将新的数字类型写入模板文件中else GetTeZheng ;try mytezheng- value inputdlg.m_value1;cf.SeekToEnd ;/定位当前文件指针到文件尾cf.Write &mytezheng- value,sizeof signed char ;/将文件数据写入当前文件位置cf.Write mytezheng- VHDerection,sizeof signed char *15 ;cf.Write &myt

4、ezheng- lenth1,sizeof signed char ;cf.Write &mytezheng- lenth,sizeof signed char ;cf.Write &mytezheng- decon,sizeof signed char ;cf.Write &mytezheng- lenfirst,sizeof signed char ;cf.Write &mytezheng- lenend,sizeof signed char ; catch CFileException *e /Alert user to errore- Delete ;

5、/end try-catch /end if-else /end if /end ifreturn; 4、识别程序void CPatternView:OnRecognize void cf.SeekToBegin ;int nFileSize cf.GetLength ;int i nFileSize/sizeof TEZHENG ;TEZHENG *temp;temp TEZHENG * malloc sizeof TEZHENG ;/计算特征值GetTeZheng ;/在模板文件中寻找，是否有与当前特征值相同的for int j 0;j i;j+ cf.Read void * temp,s

6、izeof TEZHENG ;for int k 0;k 15;k+ if temp- VHDerectionk! mytezheng- VHDerectionk break; /找到识别结果if k 15 && temp- decon mytezheng- decon && temp- lenfirst mytezheng- lenfirst && temp- lenth1 mytezheng- lenth1 && temp- lenth mytezheng- lenth && temp- lenend myte
