图像压缩主要目的是为了节省存储空间，增加传输速度。图像压缩的理想标准是信息丢失最少，压缩比例最大。不损失图像质量的压缩称为无损压缩，无损压缩不可能达到很高的压缩比；损失图像质量的压缩称为有损压缩，高的压缩比是以牺牲图像质量为代价的。压缩的实现方法是对图像重新进行编码，希望用更少的数据表示图像。-The main purpose of image compression to save storage space, increase the transmission speed. The idea

Speech compression using Linear Predictive Coding.
LPC is the oldest and the most basic of modern speech coders. Its a lossy scheme. Playback quality isn t preserved in the process but it can be used in low bit-rate systems.
