DU Lie-bo, LU Qin, XIAO Xue-min. Low-power JPEG2000 realization for camera node in wireless sensor networks[J]. 2009, 28(1): 27-29. DOI: 10.13873/j.1000-97872009.01.020.
The amount of image data gathered by camera nodes in WSNs is very large.They need to be compressed before transmission.To satisfy the low-power and high image quality requirements of WSNs
The low-power JPEG2000 realization for DSP-based self-designed camera node is studied.Wavelet transform
quantification and embedded block coding are all improved to optimize its hardware implementation.Experiments results show that the improved JPEG2000 leads to a great reduction in memory requirement and implementation time
and hence saves energy comsuption of camera nodes.
