Rules of memory management of openCV

After several weeks’ hard working, finally, the memory leaking problem is fixed. 

In the last post which listed nearly all kinds of variaties declare and delete methods, here i add several tips for memory check while it is leaking:

1) int, double, float … : these kinds of variaties don’t matter so much;

2) IplImage* : this really matters, especially when cvCloneImage is conducted, if the destination variaty was not cleared, the memory would fly up.

3) CvMemStorage: be careful, to delete this data you have to use not ‘cvReleaseData’ but ‘cvReleaseMemStorage’, one declaration, one delete operation.
