A lossless compression method of JPEG file based on shuffle algorithm

The compression effect of existing lossless compression algorithm for JPEG file is poor. This paper introduces lossless compression methods combined by shuffle algorithm and lossless compression algorithm and proposes a novel algorithm. Combining this algorithm and universal lossless compression algorithm, we compress losslessly to JPEG file. The results show that this method can further remove the internal documents redundancy and reduce the file size.
