Recognition of human actions is usually addressed in the scope of video interpretation. Meanwhile, common human actions such as "reading a book", "playing a guitar" or "writing notes" also provide a natural description for many still images. In addition, some actions in video such as "taking a photograph" are static by their nature and may require recognition methods based on static cues only.
