By applying a different compression strategy to each of these types of data , better results can be achieved than with traditional compression techniques 通过对每一种类型的数据应用不同的压缩策略,可以得到比用传统压缩技术更好的结果。
As an efficient data compression technique , vector quantizaton is known for its low bit rate , simple decoding and minor distortion 矢量量化是一种高效的数据压缩技术,以压缩比大、解码简单和失真较小著称,已被广泛应用于图像和语音压缩领域。
Ice ecc uses special compression techniques for storing catalogs of files . it provides the minimal size of recovery files even for large file collections Ice ecc对于存储文件的目录使用特殊的压缩技术。即使对于大的文件集合,它也提供最小大小的恢复文件。
That advance and further improvements in pulse compression techniques have resulted in pulses that have the maximum possible intensity for a given energy of light 有了这个进展,再加上脉冲压缩技术的改良,我们终于能够使固定能量的光产生出最强的脉冲来。
A new data compression technique , called the threshold discrete fourier transform ( tdft ) method , is proposed to efficiently compress the scattered field data from complex targets 提出了阈值dft ( tdft )算法用于实现基于雷达目标强散射中心分布的rcs数据压缩。
Around 10k block size , block - level compression starts to look moderately good ; and at 100k block size it becomes very close to the file - level compression techniques 块大小约为10k时,块级别压缩开始显得比较不错;块大小为100k时,块级别压缩就非常接近文件级别压缩技术了。
For both styles of documents for every compression technique , the size differences in compressed files is much smaller than between the xml versus text originals 对于两种风格的文档而言(对于每种压缩技术) ,已压缩文件中的文件大小差异比xml和文本原始文件之间的差异要小。
Providers can ensure video quality by applying algorithmic compression techniques such as chroma subsampling , which uses color variation undetectable to the human eye 供应商通过应用诸如色彩子取样等算法压缩技术确保视频的质量,所谓的色彩子取样使用了人眼观察不到的颜色变化。
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。
