This scheme adapts to hardware implementation too . using the scheme given by this paper relatively satisfying result is gained , comparing with jpeg and single adaptive huffman compression 与应用jpeg的无损压缩和单趟的自适应huffman压缩方法比较，得出了较为令人满意的结果。
A compression method that modifies its operations and / or its parameters according to the new data read from input stream . data compression techniques in which no data is lost 一种根据从输入的数据流中读出的新数据改变其运算或参数的压缩方法。采用这种压缩技术压缩的数据不会损失。
After introducing wavelet packet , a new method for data compression , based on embedded zerotree wavelet , is presented and applied to power system fault data compression 在描述小波包变换的基础上，提出了一种由嵌入式零树编码算法改变而成的应用于电力系统一维故障数据压缩的压缩方法。
Mpeg file integrates in - frame compression and between - frame compression . it has good graph quantity while the compression ratio is high . therefore , the storage space is saved Mpeg文件综合了帧内压缩和帧间压缩方法，在压缩比较高的同时保证了很好的图像质量，这样节省了存储空间。
Experiment results shows that the recovered document image compressed with this method has a higher visual quality over the standard jpeg method under the same compression ratio 实验结果表明，本文方法与标准jpeg压缩方法相比，在相同压缩比的情况下，重构图像质量明显优于标准jpeg压缩方法。
Tradition image compression method mostly consider information theory instead of vision character . so it is not satisfy the people " s need on compression ratio and revert quality 传统的图像压缩方法主要从信息论的角度出发，没有考虑视觉特性，在压缩率和恢复图像的主观质量上不能满足人们的要求。
But vliw architecture characters its wide instruction bandwidth . aiming at solving this disadvantage , a vliw model is built and a novel method of instruction compression is presented 首先建立了一个vliw模型，对该模型提出了一种新型的指令压缩方法，该方法是由水平方向和垂直方向压缩方式相互结合。
Video compression at low bit - rates has become the focus of research in the signal processing community due to the expanding applications in video conferencing on n - isdn and wireless video communications 随着基于n - isdn和无线信道的视频通讯需求的增长,低比特率下的视频压缩方法已经成为热点研究课题。
