to get the average of two frames, I found this simple code in opencv.

Mat img_mean=0.5*image+0.5*image2;
imshow("Average",img_mean);

But I get this error that Double can not convert to the Mat.

How do I solve this erros?

Try:

 Mat img_mean = image * 0.5 + image2 * 0.5;

If I am wrong, then read docs cv::Mat (overloading operators section)

scaling: sc1 = image * 0.5;

scaling: sc2 = image2 * 0.5;

plus: sc1 + sc2.

In total: (image * 0.5) + (image2 * 0.5)

In total: (scaling) plus (scaling).
