Image processing performance analysis for low power wireless image sensors

Abstract

This paper presents an analysis of an image processing performance requirements of a low power wireless image sensors network for video-surveillance. The specifications on the processing algorithms considered are: low complexity for a low power hardware-software implementation, high image compression for reducing wireless transmission power and bandwidth, acceptable image quality for video-surveillance applications under bad illumination conditions and in presence of noise in the wireless channel. The specifications have been defined for a possible implementation of the image wireless network over the low cost, low power but low rate Zibee wireless protocol.
