Abstract :
In this paper, by analyzing the characteristics of the data, we adopt lossless compression based on predictive coding method. First, we adopt two-way differential prediction for data, and then use the three classical adaptive compression algorithms, and have made a good compression ratio. Then, we tested our algorithms and compared with Winrar software, and our algorithm is superior to it using our test data.
