摘要
本文在讨论 JPEG标准压缩过程的基础上 ,提出了自适应优化匹配量化表的 JPEG图像压缩方法。该方法根据每个图像子块不同的频率特性确定不同的量化表。本文通过一系列的图像实际压缩实验 ,证明了该方法的有效性和可行性。
Having discussed the standard process of JPEG,we put forward an adaptive optimizing matching quantization technique f or JPEG,which is based on choosing different quantization tables according to fr equency characteristics of each image blocks.A serial of experiments is finished ,and the validity and feasibility of the method are verified.
