Sensarea: An authoring tool to create accurate clickable videos

We present a user-friendly software application that can be used in a post-production environment and that allows to automatically or semi-automatically perform spatiotemporal segmentation of video objects. The central element in the application is a local pyramid-based segmentation algorithm. Several tools are provided to interactively guide or correct the automatic process when necessary. The masks of the extracted objects can be exported in a Flash or XML vectorized format and can be synchronized to the original video for many applications such as clickable videos.
