中文摘要：

为了改善各种算法对JPEG文件无损压缩效果不佳的问题，改进了一种洗牌算法和无损压缩算法相结合的无损压缩专利方法。通过实验验证，改进算法能够进一步去除JPEG图像文件中的少量冗余，算法表现出了强劲的压缩性能。得出结论：提出的改进算法能进一步无损去除文件内部冗余，减小文件体积，算法简单，时间复杂度低，易于实现。

英文摘要：

In light of poor performance in lossless compression of JPEG, combined with the reality, a new improved idea of the lossless compression patent algorithm which using shuffle is proposed. The correctness of simulation result is verified by experiment. The improved algorithm can eliminate redundancy in JPEG. The image compression efficiency of new algorithm is analyzed. The results show that the algorithm＇s principle is simple and it is easy to realize.
