In recent years, techniques for diminishing objects from images are actively researched. These technologies are used for multiple applications such as privacy protection for people who are unconsciously in images. However, conventional methods have constrains such as “multiple cameras required”, “the objects to be diminished is required to be static”, “the background must be a plane.” In this research, we propose a method for diminishing people in an image sequence using a single handheld camera. We suppose that the scene is dynamic of which both photographer and people to be diminished are moving while the video is being recorded. In additon, the background can be arbitrary shape because we reconstruct 3D shape of it. In the experiment, we compare the proposed method with existing methods for different scenes which have various backgrounds.
