摘要
在数据采集和数据传输系统中常运用数据压缩技术,数据压缩通常可分为无损压缩和有损压缩两种。结合常用数据无损压缩算法原理,给出了实现流程图,并着重讨论各算法的优缺点,最后分析了在实现与优化算法过程中需要注意的问题。
The data compression technology is often used in data collection and data transmission systems.Data compression can generally be classified into lossless compression and lossy compression.First,the principle of the commonly used data compression algorithm is introduced, and then this paper focused on the advantages and disadvantages of each method. At last, some problems that need to pay attention to in use are given.
