  • providing a reference mask representing a trade mark;

    capturing frames from the video stream;

    searching each captured frame using the reference mask to determine a respective correlation value indicative of the likelihood of the presence of the trade mark of the mask in that captured frame in dependence upon correlation between the mask and part of that captured frame; and

    calculating a brand exposure value for the video stream in dependence upon the determined correlation values.
