—Power efficiency is a key issue in wireless sensor networks due to limited power supply. Buffer management is also crucially important in the scenario where the incoming traffic is higher than the output link capacity of the network since a buffer overflow causes power waste and information loss if a packet is dropped. There are many available buffer(More)
In this paper, we proposed a hand gesture control framework on smart glasses. Three different camera structures were presented to detect the hand portion, and the Moore's Neighbor tracing algorithm detects the hand contour more efficiently and automatically. We not only refined the skin-color model but also improved the Chamfer matching method for the(More)
