低速率编码 meaning in English
lre low rate encoding
Examples
- At low bit - rates , because of limitation of the budget bits , we can make the quality of regions absorbing eye focus higher than other regions by adjusting bit - allocation
在低速率编码条件下，由于总的允许分配比特数量有限，通过调整位分配过程，可以使得某些人眼感兴趣的区域的图像恢复质量高于其它区域。 - Digital speech has preponderance over analog speech in reliability , robustness and security during communication . however , digital speech needs more bandwidth than the analog signal . especially with the requirement for communication frequency increasing , it ' s necessary to code speech signal at low rates
但是，数字化后的信号所占的频带大幅增加，特别是在带宽需求日益增长的今天，这个问题尤为突出，因此语音的低速率编码(即压缩编码)成为迫切的要求。 - In order to improve coding efficiency at low bit - rates , this thesis adopted wavelet and nonlinear matching pursuit techniques , combined with some characteristics of human visual system , aimed at improve the performance of video coding at low bit - rates . the major contributions of this thesis are included in the following : 1
