信息化战场静态图像传输抗误码策略

Anti-Error Code Strategy during the Static Image Transmitting in the Informative Battlefield

信息化战场上,图像的分解与恢复是增强静态图像传输抗误码性能的关键问题之一。基于重叠正交变换的多描述编码方法分解图像,采用最大图像平滑恢复算法与空域误码掩盖算法相结合的方法恢复分解后的图像,在详细理论推导的基础上,得出了信息化战场静态图像传输的抗误码策略。最后,通过JPEG2000编解码器开放测试模型Jasper中的仿真实验验证了该方法的可行性。

The decomposing and restoring of the image play a vital role in strengthening anti-error code capability during the static image transmitting throughout the informative battlefield. The image is decomposed with a method of multi-depicted coding based on the overlapped cross-transform, and then the decomposed image is restored with a combined method of the Maximally Smooth Image Recovery algorithm and the space error code covering algorithm. This thesis brings forward the strategy of anti-error code created during the static image transmitting, based on the delicate theoretic deductions. Finally, the strategy is proved feasible by simulative experiment operated in the Jasper Model, an opening test model in the JPEG2000 coder-decoder.
