c - C和OpenCV内存泄漏

我的内存泄漏有问题。在这个简单的程序中:

#include <stdlib.h>
#include <stdio.h>
#include "opencv2/core/core.hpp"
#include "opencv2/highgui/highgui.hpp"

int main() {
    CvMat *src;
    src = cvLoadImageM("p1.jpg", CV_LOAD_IMAGE_GRAYSCALE);
    cvSaveImage("p2.bmp", src, 0);
    cvReleaseMat(&src);
    return 0;
}

根据valgrind，有7个泄漏:

==10478== HEAP SUMMARY:
==10478==     in use at exit: 10,464 bytes in 7 blocks
==10478==   total heap usage: 154 allocs, 147 frees, 2,908,450 bytes allocated
==10478==
==10478== LEAK SUMMARY:

有人可以告诉我如何正确释放内存吗？感谢您的意见。

@ user4815162342可能是正确的。
尽管我建议您迁移到新的C++ OpenCv cv::Mat，通过它自动进行内存管理。
