摘　　要：从无线视频传感器网络能源受限的特点出发,针对重建图像质量要求不高的情况,基于SPIHT算法,提出了一种在节点的消隐方式小波编码方法。它能降低编码过程的能耗,适合于无线视频传感器网络的应用要求。实验证明,该算法在低码率、短距离的图像传输中节能效果显著。In response to the features of the limited energy in wireless video sensor networks,based on SPIHT（Set Partitioning in Hierarchical Trees）,an in-node wavelet coding method run in the elimination mode is proposed according to the low requirement of the image quality,which is more suited for the application of the wireless video sensor networks for saving more energy in coding.The experiments show that the method has a good effect on energy conservation,which is more obvious in the transmission of low rate and short distance.
