This article proposes a novel mechanism for continuous objectboundary region detection. Different from others work, we work on a fog computing environment where a few sensor nodes are deployed. This means that sensing holes may exist in network regions. Based on sensory data, we interpolate on network region and find a predicted objectboundary line. To cover sensing holes and detect the real boundary, mobile sensors are adopted to traverse the selected stops on boundary line. Last sensory data gathered by mobile sensors help to draw a more precise boundary area. Experimental evaluation shows that the proposed technique can detect a precise objectboundary region timely and sensor nodes can work in an energy-efficient manner.

A novel and effective modification of the original Snake algorithm is proposed, The modification can improve the capability of the algorithm to detect boundaries with shop corners or concave parts without the need to introduce external forces. The essential idea is to apply conformal mapping to transform the image so that the objectboundary in the new domain can be captured by the Snake algorithm.
