Algorithm for Multiple Description Image Coding Based on Wavelet Transform and Set Partitioning In Hierarchical Trees
Huiping Deng · 2007
On the basis of EZW-based(embedded-zero wavelet tramsform)multiple description coding algorithm,an improved algorithm for multiple description image coding is proposed in combination of wavelet transform with the algorithm of multi-grade set separation,its principle is deseribed.Matlab is used to simulate the program of the 2 algorithms.The results shows that under the same conditions the later can obtain a reconstructed image with its quality higher than that of the former(except for receiving all the descriptions),by which the robustness of data transmission is improved.
