The object tracking is critical to visual / video surveillance, analysis of the activity and gesture recognition. The major difficulties to be occurred in the visual tracking are different environmental conditions, illumination changes, occlusion and appearance. In this paper, the comparative analysis of the different systems which are used to recognize the head gestures under different environmental conditions is discussed. The existing algorithm used to recognize the head gestures has some limitations. The existing algorithm cannot work under outdoor environmental conditions. The traditional camshift algorithm and unscented kalman filter are integrated and used to recognize the head gestures under outdoor environmental conditions. The unscented kalman filter is a tracking algorithm used to remove the limitations of the traditional camshift algorithm. The simulation result shows the better performance of the improved algorithm than the traditional camshift algorithm.

In this paper, the hand gesture of a person is recognised and it identifies which hand of the person is raised. The skin colour is taken to recognise hands and face and the dark background is taken so that the skin detection may become easier. The hands and face are differentiated on the basis of area and centroid. Camera is the only input device used in this algorithm. No other input device is used to differentiate hands from the remaining body. This algorithm can be used both on the captured images and real time images.

In this paper, we focus on using pointing behavior for a natural interface, Hand gesture recognition based human-machine interface is being developed vigorously in recent years. Due to the effect of lighting and complex background, most visual hand gesture recognition systems work only under restricted environment. To classify the dynamic hand gestures, we developed a simple and fast motion history image based method. In recent years, the gesture control technique has become a new developmental trend for many human-based electronics products. This technique let people can control these products more naturally, intuitively and conveniently. In this paper, a fast gesture recognition scheme is proposed to be an interface for the human-machine interaction (HMI) of systems. This paper presents some low-complexity algorithms and gestures to reduce the gesture recognition complexity and be more suitable for controlling real-time computer systems.

In this paper, Hand-Gesture Recognition System helps the dumb people finding difficult in communicating with the society. These people give some gestures to communicate with the normal people but all the gestures given by the dumb cannot be understood. So,there is a necessary to have some media between the dumb and normal people. The system recognizes the gestures given by the dumb and display the message on the LCD according to the gesture. The glove with flex sensors is worn to the hand of the dumb and when the gesture is given it is sensed by the flex sensor then the system recognize the gesture. Paraplegics are the persons whose body parts below the belly will not work and find difficulty in using the appliances. The system also consists of accelerometer control the fan and light. The appliances can be controlled by tilting the accelerometer. An alert message with the help of a GSM can be sent to the concerned person of the paraplegic when the paraplegic is in trouble.
— Gesture is a way of Human Computer Interaction. It is a technique that is mainly carried out to make impaired community communicate with normal humans. It's main aim is to convey human gestures to computing device. They are efficient for natural and intuitive human-computer interaction. To achieve this goal, computers should be able to visually recognize hand gestures from video input. We propose a new architecture to solve the problem of real-time gesture recognition. The fundamental idea is to use a combination of hand gestures to control various functionalities. This will include two parts, first is to track the movement of the hand and secondly is to track the orientation of the hand. This paper presents a robust and efficient technique for gesture recognition. The OpenCV library provides us a greatly interesting demonstration for object detection. Furthermore, it provides programs (or functions) that they used to train classifiers for their gesture detection system, called HaarTraining, so that we can create our own object classifiers using these functions. Our working environment is Visual Studio on Windows 7. The objective of this project is to develop an application for recognition of hand gestures with reasonable accuracy and thus creating windows media player compatible remote control.

For persons with severe disabilities who find it difficult to operate the joystick or the chin stick of an electric wheelchair, we have developed an interface that allows the wheelchair to be operated by gestures such as head movements. By using a camera to perform visual sensing, we aim to implement a non-contact non-constraining interface where no wires or equipment of any kind have to be attached to the user, thereby making the interface much more convenient to use. Range information obtained from a stereo camera is used to control the electric wheelchair in any situation regardless of whether it is used indoors or outdoors. We are keeping this study user-oriented by performing clinical trials with the help of actual users to determine where the camera should be situated, how it should be used, and so on.

This project describes the motivation and design considerations of an economical head operated surveillance camera for people with disabilities. In addition, it focuses on the invention of a head-set operated device to control the movement of the camera, such that the camera can turn left and right according to the movement of the human head. It employs one tilt sensor, which placed in the headset to determine head position and to function as simple headset control system. The tilt sensor detects the lateral head motion to drive the left or right displacement of the camera. This system was invented to assist people with disabilities to live an independent life or even allow them to work as security personnel to earn their life. The idea can be employed in other application such as robotics, intelligent home devices and vehicle control as well.

A recognition method for simple gestures is proposed and evaluated. Such gestures are of interest as they are the primitive elements of more complex gestures utilized in natural communication and human computer interaction. The input to the recognition method is obtained from a head tracker that is based on images acquired from a depth camera. Candidate gestures are detected within continuous head motion and recognized, acknowledging that head pose estimates might be inaccurate. The proposed method is evaluated within the context of human-computer dialog.The reported results show that the proposed approach yields competitive recognition results to stateof-the-art approaches.
