OpenCV程序内存泄露的预防与检测 I. 内存泄露首先我们要搞清楚什么是内存泄露。一个应用程序在运行时占用内存区域可以分为五个：栈区、堆区、自由存储区、静态区、常量区（不讨论代码区）。栈(Stack)区存放局部变量，也就是在一个函数或代码段中定义的变量，局部变量由系统自动进行分配和释放；堆(Heap)区和自由存储区存放我们程序运行过程中动态分配的内存，主要由C语言的malloc函数和C++的new运算符进行分配（Open 阅读详情

在我自己写的类里面添加了Mat类型的变量，在任何地方都没有使用该变量，也没有使用CKeyPoint类，都会发生内存泄露问题。这是为什么？怎么解决呢？谢谢了！



class CKeyPoint

{

   private:

	Mat  m_phplane;

};

在关闭（执行 OnClose函数）就造成内存泄露了，泄露的内容是

这个问题怎么解决啊？谢谢啦！
