An method to determine brand or advertisement exposures in media content comprises: determining whether a scene detected from a media stream corresponding to the media content matches 614 a reference scene; identifying 620 an expected region of interest (ROI) in the detected scene, based on information describing the reference scene, when (a) the detected and reference scenes match and (b) the reference scene is not specified to be of no interest 618; and determining 621 whether a known, reference brand identifier associated with the reference scene is in the expected region of interest. An associated apparatus comprises a scene detector, dividing scenes into a sequence of image frames, each with similar signatures; a scene classifier also compares detected scenes to plural reference scenes to assess scene interest. Also independently claimed is a system, using a similar reference-comparison and ROI prediction method, comprising an audience measurement system, combining embedded brand information with audience exposure data. Further independently-claimed methods, to specify a ROI, relate to modification and reshaping of an initial template that represents a region of interest. |
