A Threshold-based Rate Optimization Algorithm for Image Transmission
An optimal bit rate allocation algorithm for image compressed with SPIHT is proposed. A threshold-based transmission scheme of SPIHT bit streams and a rate optimization algorithm based on threshold after analyzing the characteristics of SPIHT bit stream are developed in this paper. Simulation results show that, the proposed technical solution is better than the traditional bit stream allocation schemes in terms of the packet number used to decode and PSNR of reconstructed image. Therefore, the scheme is more potential and practical for future efficient and reliable wireless multimedia communication systems.
