  When we watch a video, in which human hands manipulate objects, these hands
may obscure some parts of those objects. We are willing to make clear how the
objects are manipulated by making the image of hands semi-transparent, and
showing the complete images of the hands and the object. By carefully choosing
a Half-Diminished Reality method, this paper proposes a method that can process
the video in real time and verifies that the proposed method works well.
