We present an interactive tool for the exploratory analysis of a long-term video from a stationary camera. The tool consists of three key methods: spatial change visualization, temporal change visualization, and similarity-based video retrieval. The first two methods summarize the long-term video, letting the user know where and when changes frequently occurred during a certain period, allowing the user to find an event of interest from the video. With the third method the user can search the
