OpenCV Error: Insufficient memory

Question

I'm developing a project with opencv 2.3 in c++ style.

In the application I load a video and process every frame and do some stuff with the Mat object. After some time I get a Insufficient memory Error.

I capture the frame like:

FCapture >> FImage; 
FDetector->execute(FImage); 

In the execute I copy the image and save it in a std::Vector list. And also check the imageblobs like:

vector<vector<Point> > contours; 
findContours(FImage, contours, CV_RETR_EXTERNAL, CV_CHAIN_APPROX_SIMPLE); 

I know its a bit difficult to answer where the problem could be, but it's impossible to post here to whole program code. Maybe someone could tell me where I have to be careful to copy Mat objects or other OpenCv object that could be the reason of the error.

Answer 1

Interesting:

In the execute I copy the image and save it in a std::Vector list

and this statement as well:

After some time I get a Insufficient memory Error.

OpenCV images can be quite big depending on their size, and based on what you said, I think that your vector is growing faster then you can remove data from it , causing the insufficient memory error.

Makes sense right? If you keep adding data to the vector, one day you'll run out of memory to store new data.
