For simple black and white images, you can try compare:

cv::Mat img1 = ...
cv::Mat img2 = ...
cv::Mat result = ...

cv::compare(img1 , img2  , result , cv::CMP_EQ );
int percentage  = countNonZero(result);

However, for more advanced comparisons, there are different approaches such as extracting matching areas with matchTemplate
