We present in this paper, new method for recognizing hand postures from their shapes. Firstly, convex and concave points with high curvature values are extracted from the contour of the hand's posture shape. Then curves are fitted to the concave points. These curves are used for partitioning 2D hand's posture shape into subparts representing the fingers and(More)
Abstract— In WSN, sensor nodes have a limited transmission range. In fact, their processing and storage capabilities as well as their energy resources are also limited. However, regular routing protocols for wireless devices are not well suitable for sensors due to the constraints of their resources. These protocols ensure the duty of maintaining network(More)
