Research of Image Transmission System Based on ZigBee and GPRS Network
International Journal of Machine Learning and Computing, 2013Co-Authors: Da Zhang, Xiao LvAbstract:It is urgent to need the rich information of the Image etc. introduced into wireless sensor network based monitoring. This paper introduces an Image Transmission system based on wireless sensor networks using the ZigBee and GPRS network. The ZigBee network uses mesh network topology, which is simple and robust. To realize the remote Transmission, this paper uses GPRS network, and it can realize seamless connection of the ZigBee Coordinator node, GPRS and the internet. Through the Image Transmission system, it can quickly transmit the Image to the monitoring center, and the monitoring center can composite the Image by the transmitted Image data from ZigBee End-Device. Through the Image Transmission system, it can make up Transmission data single by WSNs. It will have a fine application prospects in the Image monitor system.

New scheme for Image Transmission based on SPIHT
Journal of Computer Applications, 2013Co-Authors: Fu Yao, Liu QingliAbstract:In this paper,a new real-time Image Transmission scheme based on Set Partitioning In Hierarchical Tree(SPIHT) was proposed.Firstly,the Image data needed to be transformed by wavelet.Secondly,in order to resist error pervasion when Image was transmitted,the wavelet coefficients were separated into small blocks and encoded by SPIHT.Finally,in order to improve the quality of the restructured Image,the wavelet coefficients of the highest level in every block were transmitted repeatedly.In order to improve the throughput of the Image Transmission system,the optimum frame length was proposed.Both theoretical demonstration and simulation results here have validated that the proposed scheme provides stronger error resilience than traditional scheme based on SPIHT,and can improve the peak signal to noise ratio of the restructured Image about 10 dB.

A Low-Complexity UEP Image Transmission Scheme over Satellite
International Journal of Machine Learning and Computing, 2013Co-Authors: Xiaoyong Wei, Fan Yang, Ding ZheAbstract:Image Transmission over satellite is an important application in our life. The unequal error protection (UEP) fountain coding is able to avoid the backchannel reTransmission, and also provides UEP for the embedded compressed multimedia data. Thus it has become the ideal solution for Image Transmission scheme over satellite. However, the complexity of the existing UEP fountain coding hinders the applications on energy-constraint satellite. In this paper, a low-complexity UEP Image Transmission scheme is proposed. Two elements are designed to reduce the complexity of our Transmission scheme. First, a very low-complexity Image coding algorithm, the improved SPIHT (ISPIHT), is adopted as our compression codec, which provides almost same compression performance as JPEG2000 but much fast coding speed. Second, the descent method based optimization algorithm is proposed to further simplify the computational complexity. With these two elements, our proposed UEP Image Transmission scheme is very applicable for satellite communication. Finally, our simulation results show our low-complexity UEP Image Transmission scheme outperforms the traditional EEP scheme.
