ConvertTo 函数中 Mat 的内存泄漏

我在管理函数中的内存时遇到一些问题。 Valgrid 说我在转换函数后出现内存泄漏。难道是因为数据没有正常发布？我尝试使用临时指针，但我的程序崩溃或无法正常工作。以前有人遇到过这个问题吗？

this->images.push_back(new cv::Mat());                                                          //ID
cv::threshold(*this->images[MASK], *this->images[ID], 0.0, 1.0, cv::THRESH_BINARY);
this->images[ID]->convertTo(*this->images[ID], CV_32SC1);

这是 valgrid 输出：

==5663== 64,339,996 bytes in 1 blocks are possibly lost in loss record 380 of 380

please don't将指向 Mat 的指针存储在向量中（或其他任何地方！）。

这些东西在内部重新计数，就像智能​​指针一样，并且您通过存储/复制指针来破坏它（无论如何，指向智能指针的指针向量听起来很愚蠢，不是吗？）。

使用普通的vector<Mat>，用每件额外的约 56 字节换取今晚的酣睡；）
