Energy is an important consideration in the design and deployment of wireless sensor networks (WSNs) since sensor nodes are typically powered by batteries with limited capacity. Since the communication unit on a wireless sensor node is the major power consumer, data compression is one of possible techniques that can help reduce the amount of data exchanged(More)
The snakes algorithm is an image segmentation process that utilises energy-minimising splines. The energy terms are obtained from discrete points that make up a snake and the gray-level values in an image. An algorithm for automated positioning of the initial snake points is presented by the authors, together with two additional energy terms (intensity and(More)

To monitor a small region of skin tissue for blood perfusion mapping construction, a Y-Z scanning control system using X-Y mechanism was developed. This control system utilizes the combination of a Stepper Motor and a DC Motor. A GCP (Graphical Coded Programming) of LabVIEW is used to compute the system driver controller via DAQ (Data Acquisition) card of(More)
