JPEG image compression algorithm analysis and local optimization

The purpose of this paper is to analyze and further optimize the JPEG image compression algorithm. First we analysis of JPEG image compression algorithm to achieve the specific methods with the advantages and disadvantages, at the same time, in the algorithm module in the sending, the output of a new data transfer mode was developed to reduce the error rate and enhance perform well in the data transfer rate based on the algorithm local optimization. In the end, we proved that the new data transfer mode can efficiently improve the data transfer rate and reduce the error rate through an experiment.
