Interacting with physical world using expressive body movements is much easier and effective than just speaking. Gesture recognition turns up to be important field in the recent years. Communication through gestures has been used since early ages not only by physically challenged persons but nowadays for many other applications. As most predominantly hand is use to perform gestures, Hand Gestur...

Importance of human-computer interaction (HCI) systems is increasing since they revolutionized the way people interact with computers. Gesture and posture analysis, especially hand gesture and posture recognition, is one of the more recent areas in the HCI with ever widening field of applications. In this paper we propose an algorithm for hand posture recognition that is based on skin detection...

Hand gesture recognition for human computer interaction, being a natural way of human computer interaction, is an area of active research in computer vision and machine learning. This is an area with many different possible applications, giving users a simpler and more natural way to communicate with robots/systems interfaces, without the need for extra devices. So, the primary goal of gesture ...

In this paper, we propose the Perceptual Shape Decomposition (PSD) to detect fingers for a Kinect-based hand gesture recognition system. The PSD is formulated as a discrete optimization problem by removing all negative minima with minimum cost. Experiments show that our PSD is perceptually relevant and robust against distortion and hand variations, and thus improves the recognition system perfo...

Robots of the future should communicate with humans in a natural way. We are especially interested in visionbased gesture interaction. This paper describes our hand gesture recognition system that will be used in a mobile robot. It is based on our version 1.0 hand gesture recognition system. This paper focuses on the different methods we used on this new system and we will also compare the resu...

Sign Language is a language which uses visually transmitted sign patterns to convey meaning by simultaneously combining hand shapes, orientation and movement of the hands to fluently express one's thoughts / communicate with others and is commonly used by the physically impaired people who cannot speak or hear. Automatic Sign Language system requires fast and accurate techniques for identifying...
