一种基于JPEG2000的多描述编码方案

A Multiple description image coding algorithm based on JPEG2000

  • 摘要: 在JPEG2000编码算法分析的基础上,针对JPEG2000在Tier-1编码器编码输出的压缩比特流具有嵌入性的特点,提出一种新的多描述编码算法.该算法以JPEG2000中的编码块为基础,把2个经不同码率编码后的嵌入码流进行重新分配组合,形成码率相似的两重描述.实验表明,该算法表现出了优良的性能,并且能适用于各种嵌入码流的图像编码.

     

    Abstract: A new method is proposed to generate multiple descriptions of images,exploring the features of the bit stream used in the Tier-1 encoder of the JPEG2000 standard.The scheme is compatible with the JPEG2000 encoding algorithm because two descriptions with similar bit rates are generated by combining two JPEG2000 code stream with different bit rates.The method yields excellent performance in both central and side decoders.
