In this paper, we present an interactive object segmentation system form video, such as TV products and films, for converting 2D to 3D contents. It is focused on reducing the processing time for the object segmentation, increasing the usability. The proposed system is consist of three steps which are trimap generation based on polygon and object segmentation using Graph Cut algorithm and refinement by a user interfaces (UI) based on rectangle and local features. It makes it easy to get object segmentation rapidly. It is also helpful to create 3D contents.
