內存泄漏在哪裏

該代碼用於運動跟蹤。它跟蹤2張圖片的不同點。但是，每次調用函數時，內存大小都會增加很多。我知道它可能與cvPoints有關。什麼是解決問題的好方法？謝謝內存泄漏在哪裏

    // allocate the images and other structures we will need for

你在那裏有一堆'cvCreate'調用，但我沒有看到任何看起來可以釋放所有這些的東西。 – Mat 2012-08-08 18:21:57

你已經嘗試valgrind或類似？你期望這裏的人是你的衆包調試器嗎？ – 2012-08-08 18:22:59

有2個「新」。 C++在返回後是否刪除它們？ – 2012-08-08 18:23:37

看起來像你正在分配一堆內存，而不是刪除它。

嘗試添加行：

delete [] cornersA; 
delete [] cornersB;

在你的函數結束。

您也可以查看cvCreate的電話 - 如果他們沒有在其他地方被釋放，可能會導致問題。

我加了delete [] cornersA; 刪除[]角B;但仍然有很大的內存泄漏。我會試着釋放cvCreate並看看會發生什麼。 – fmvpsenior 2012-08-08 18:32:44

我發佈了所有創建的圖像，它工作。謝謝。 – fmvpsenior 2012-08-08 18:36:36

感謝CvReleaseImage你必須釋放你的IplImages。

是的，它做到了。 – fmvpsenior 2012-08-08 18:37:29
