插一个用OpenCV读写的简单例子

#include <opencv2/core/core.hpp>
#include <opencv2/imgproc/imgproc.hpp>
#include <vector>
#include <iostream>
using namespace cv;
using namespace std;

class foo{                             
public:
    vector<string> imnames;                  
    void write(FileStorage &fs) const;             
    void read(const FileNode& node);              
};

void foo::write(FileStorage &fs) const
{
    assert(fs.isOpened()); 
    fs << "{";
    fs << "nimages" << (int)imnames.size();
    for(int i = 0; i < int(imnames.size()); i++)
    {
        char str[256]; 
        const char* ss;
        sprintf(str,"image_%d",i); 
        ss = str; 
        fs << ss << imnames[i];
    }
   fs << "}";
}

void foo::read(const FileNode& node)
{
    assert(node.type() == FileNode::MAP);
    int n;
    node["nimages"] >> n;
    imnames.resize(n);
    for(int i = 0; i < n; i++){
        char str[256]; 
        const char* ss;
        sprintf(str,i);
        ss = str; 
        node[ss] >> imnames[i];
    }

}
template <class T> T load_ft(const char* fname){
    T x;
    FileStorage f(fname,FileStorage::READ);
    f["ftobject"] >> x; f.release(); return x;
}
template<class T> void save_ft(const char* fname,const T& x){
    FileStorage f(fname,FileStorage::WRITE);
    f << "ftobject" << x; f.release();
}
template<class T> void write(FileStorage& fs,const string&,const T& x)
{
    x.write(fs);
}
template<class T> void  read(const FileNode& node,T& x,const T& d)
{
    if(node.empty())x = d; else x.read(node);
}
int main(int argc,const char *argv[])
{
    //构造数据
    foo A;
    string name1="xhl";
    string name2="gyl";
    A.imnames.push_back(name1);
    A.imnames.push_back(name2);
    //存储A对象到foo.xml文件
    save_ft<foo>("foo.xml",A);
    foo B;
    //从foo.xml文件读入，返回的临时对象赋给b
    B=load_ft<foo>("foo.xml");
    //测试
    cout<<B.imnames[0]<<endl;
    cout<<B.imnames[1]<<endl;
