Abstract
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.
