Abstract:

Multimedia sensor network is an advanced form of sensor networks. It has multimedia information perception, processing and transmission capacity. For the problem of great redundancy and correlation in the collection data, a node selection approach for data compression was designed. By using the correlation model based on three-dimensional perception, it describes the relevant characteristics between the observed images data. Then the camera node selection algorithms was proposed based on correlation coefficients to reduce the spatial redundancy of sensing data. A set of comparisons are performed to evaluate the effective of our algorithms.

Key words: wireless multimedia sensor networks, correlation model, node selection, spatial redundancy
