Construction of a non-overlapping panoramic mosaic in wireless multimedia sensor networks

Abstract

As a result of the rapid development of hardware whose operation has low power requirements, a great deal of interest has been shown in wireless multimedia sensor networks for various applications. In sensor networks in which the sensor nodes are distributed randomly and have low-power cameras, the fields of view of some adjacent sensor nodes may overlap. The authors introduce a scheme for constructing a non-overlapping panoramic mosaic by transmitting partial images. In particular, a solution of the joint cost function for network lifetime and video quality is used to select the boundary lines between adjacent images. The experimental results show that the proposed scheme increases the network lifetime while providing better video quality.
