摘要
数据压缩的最终目标就是在不损失或尽量少损失有用信息的前提下,获得尽可能大的压缩比。而压缩算法的优劣,则是通过压缩性能指标进行评价的。
The ultimate goal of data compression is not loss or loss of useful information as far as possible under the premise of the greatest possible access to the compression ratio. The choice of compression algorithm is through the compression performance evaluation. This paper describes the applications and features in evaluation of different compression algorithms standards.
