To facilitate the access to computer systems, computer scientists choose to design interactive mechanisms which are more adapted than traditionally used devices such as keyboard or mouse.The use of gestures modalities has been extensively studied in recent years by the human machine interaction community.Augmented Reality is one of the mechanisms of interaction that allow implementing the humanmachine communication.Indeed, its principle is to mix the real world and the virtual world.Many applications already use Augmented Reality, particularly in the field of video games, film, business and also in the medical field which really interests us: our goal is to analyze medical images using augmented reality, it comes to insert 3D virtual objects, allowing to analysis the medical image and helping the doctor to make the right decision, on the doctor's hand.In this paper, we describe our approach of detecting and tracking of hand in a video stream, we hybridize two methods to draw more benefits from each one.The first is to detect the hand by subtraction of the background and the second is to detect the hand by skin color.
