| Abstract: | With resource-constrained wireless multimedia sensor networks,image coding and transmission must respect the trade-off among energy consumption,compression ratio and image quality.Compression of video-surveillance image sequences collected by a wireless multimedia sensor network is studied.A low-complexity image compression scheme based on change detection and adapted JPEG is proposed.For adaptation to the limited capacity of store and forward,change detection algorithm is used to locate the region of inter... |
