摘要 图像是互联网中传输信息的重要媒介,一幅没经过任何压缩处理的原始图像会给传输和存储带来很大困难。JPEG图像格式是目前最流行的图像格式,它的一个显著特点是压缩比相当高[1]。在本文笔者对JPEG标准下图像压缩的DCT基准算法和DPCM基准算法作了讨论和分析,为广大图像工作者提供很好的参考。 Image is an important transfers' s medium in network.Without Being Compressed,Image' s transfers and saving is very trouble. Jpeg' s standard as the image compression' s standard is in vogue, because it have high compressibility for image. In text,we talk about the DCT Arithmetic and DPCM Arithmetic tinder JPEG' s standard.These can give a lot of help to image' s operator.
