    The development in computer vision makes it possible to approach the interface problems from a human perspective, making the communication between computer and humans more natural [6]. When we as humans communicate, we use our voice and parts of our body
    such as our face and arms in making gestures. Recently, many attempts have been made to create system that through computer vision could be able to understand gestures [6].
    Outside the HCI framework, hand gestures cannot be easily defined. The definition if they exist, are particularly related to communicational aspect of human hand and body movement. Gestures are expressive, meaningful body motions involving physical
    movements of the fingers, hands, arms, head, face or body with the intent of : 1. Conveying meaningful information of 2. Interacting with the environment[11]. However in the domain of HCI, the notion of gestures is somewhat different. In a computer
    controlled environment, one wants to use the human hand to perform tasks that mimic both the natural use of the hand as a manipulation and its use in human machine communication (Control of Computer/Machine functions through gestures.)[12]All hand
    movements are classified into two major classes:

    In signal processing, a filter is a device or process that removes some unwanted components or features from a signal. Filtering is a class of signal processing, the defining feature of filters being the complete or partial suppression of some aspect of
    the signal. Most often, this means removing some frequencies or frequency bands. However, filters do not exclusively act in the frequency domain; especially in the field of image processing many other targets for filtering exist. Correlations can be
    removed for certain frequency components and not for others without having to act in the frequency domain. Filters are widely used in electronics and telecommunication, in radio, television, audio recording, radar, control systems, music synthesis, image
    processing, and computer graphics.
    One important application of filters is in telecommunication.Many telecommunication systems use frequency-division multiplexing, where the system designers divide a wide frequency band into many narrower frequency bands called "slots" or "channels", and
    each stream of information is allocated one of those channels.The people who design the filters at each transmitter and each receiver try to balance passing the desired signal through as accurately as possible, keeping interference to and from other
    cooperating transmitters and noise sources outside the system as low as possible, at reasonable cost.
