C和OpenCV内存泄漏
我有内存泄漏的问题。在这个简单的程序中:C和OpenCV内存泄漏,c,opencv,memory-leaks,C,Opencv,Memory Leaks,我有内存泄漏的问题。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("
#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;
}
有人能告诉我如何正确地释放内存吗?谢谢你的建议。@user4815162342可能是对的。
尽管我建议您迁移到新的
C++
OpenCv
cv::Mat
,通过它可以自动进行内存管理。我已经多次看到这种漏洞。检查您发送的内容上面的详细错误。这可能是pixman库。您没有证明内存泄漏,只是valgrind抱怨内存泄漏。复杂库有时使用分配模式,这些分配模式被valgrind等工具误传为泄漏。(示例包括分配池,或者出于性能原因在退出时不运行析构函数。)测试是否正在处理实际内存泄漏的一种简单方法是将main()
的全部内容(除了return
语句)包装在无限循环中。启动进程,并使用top
或等效工具观察它:如果它的内存无限增长,那么您手头上就有泄漏。
