研究目的
The objectives of this paper are twofold. The first is to timely and accurately achieve the detection of floating debris in dynamic waters and identification of salient regions in static waters. The second is to demonstrate the effectiveness and feasibility of the proposed algorithms through laboratory and field experiments.
研究成果
The proposed methods are effective and feasible and can be applied to water environment monitoring based on camera sensor nodes. The ongoing and future research will be extended to track the movement of floating debris by adjusting the orientation of the sensor node and implement an energy-efficient image communication against packet loss over wireless sensor networks.
