c++ - OpenCV-cvExtractSURF导致内存泄漏？

我正在使用OpenCV函数:cvExtractSURF，但是发现主要的内存泄漏。有人成功实现了此通话吗？

我的代码如下:

IplImage *cvImage = [self CreateIplImageFromUIImage:image grayscale:YES];

CvMemStorage* storage = cvCreateMemStorage(0);

CvSeq *objectKeypoints = 0;
//CvSeq *objectDescriptors = 0;

CvSURFParams params = cvSURFParams(self.hessianThreshold, 0);
double tt = (double)cvGetTickCount();

//Extract the features
cvExtractSURF( cvImage, 0, &objectKeypoints, NULL, storage, params, 0);

tt = (double)cvGetTickCount() - tt;
//NSLog(@"%d features found in %gms seconds\n", objectKeypoints->total, tt/(cvGetTickFrequency()*1000.));

cvReleaseImage(&cvImage);
cvReleaseMemStorage(&storage);

有什么想法可能会泄漏吗？当我注释掉该行时:

cvExtractSURF( cvImage, 0, &objectKeypoints, NULL, storage, params, 0);

没有泄漏发生。

最佳答案

函数cvExtractSURF创建一个CvSURFPoint类型的对象列表，并将指向它的指针放在objectKeypoints中。您必须释放它。

添加通话...

cvRelease((void **)&objectKeypoints);
