 printf("\n母亲=%s",248)"> }
 

1.写XMl文件,

[html]view plaincopy 
   
voidCrecognitionDlg::storeDirectoryFaces(){ CvFileStorage*fileStorage;
 fileStorage=cvOpenFileStorage("directoryInfo.xml",CV_STORAGE_WRITE);
 cvWriteInt(fileStorage,"nFaces",indexFaces.size());
 cvStartWriteStruct(fileStorage,"CVFaceRecog",CV_NODE_MAP);
 for(size_ti=0;i<indexFaces.size();i++)
 charperson[100];
 sprintf(person,"person_%d",(i+1));//必须区分开，否则读的时候会出问题
 cvStartWriteStruct(fileStorage,person,CV_NODE_MAP);
 cvWriteInt(fileStorage,"index",indexFaces.at(i));
 cvWriteString(fileStorage,"name",namePerson.at(i));
 cvWriteString(fileStorage,"directory",pathFaces.at(i));
 cvEndWriteStruct(fileStorage);
 cvReleaseFileStorage(&fileStorage);
 }

写完的内容如下：
