The task of hand gesture recognition is highly challenging due to complex background (i.e. disturbance), presence of non-gesture hand motions, and various illumination environments. The proposed techniques begin by detecting the hand, tracking the hands movements and analysing the variations in the hand locations (i.e. Motion detection), and finally recognizing the appropriate gesture. Since the introduction of new gesture recognition technologies, interactive hand-gesture devices (such as smart televisions and displays) have been rapidly emerging.
