ABSTRACT

As we have seen in the previous chapters, there are many aspects to multimedia semantics. Multimedia contents may represent various objects or events, some of which may have contextual importance. Some obvious examples are discovery of a firearm in the x-ray image of baggages scanned at an airport or interpretation of a sequence of frames in a video as a sports event, such as scoring of a goal in a soccer tournament. There are other subtle aspects of multimedia semantics beyond object or event recognition. For example, different configurations of the human faces and different composition of melodies depict various human emotions, and the brushstrokes on paintings often characterize the artists or the schools they belong to.
