摘要:
 实时解压缩算法需要解决的两个主要问题是快速纠正信道噪声导致的数据错误和实时处理大量的压缩数据。针对这两个问题,在现有JPEG2000解压缩算法的基础上,提出一种实时解压缩算法。该算法基于蒙特卡罗方法和JPEG2000压缩数据结构特点引入快速数据纠错算法,提高了算法的容错能力;同时优化了现有解压缩算法的结构,提高了解压缩算法的速度。实验结果表明,实时解压缩算法与现有的JPEG2000解压缩算法相比速度提高了30%,满足了实时解压缩的要求,并且保证了图像质量。
Abstract:
 Two major problems that need to be addressed are quickly correcting the error data which is caused by the channel noise and re-al-time processing a great deal of compression data in the real-time decompression. A new real-time decompression algorithm based on the existing JPEG2000 decompression algorithm is proposed. This new algorithm brings high-speed error resilience method into JPEG2000 decompression algorithm and optimizes the existing JPEG2000 decompression algorithm’ s structure. The high-speed error re-silience method is based on the Monte-Carlo method and the feature of JPEG2000 compression data’ s structure. The experimental results demonstrate the new real-time decompression algorithm can improve the speed of decompression by 30%,which meets the requirements of real-time decompression,and guarantees the quality of the image.
