加权滤波器 meaning in Chinese
weighting filter
Examples
- Emulation results show that the modified feel weighted filter can reduce the effect of the noise interference by taking good use of the masking effect
结果表明,修正后的感觉加权滤波器更好地反映出合成滤波器的变化情况,更好地利用了掩蔽效应降低了噪声干扰的影响。 - In section two , we introduce some of the main coding theories that was in the g . 729 , including the digital model of the production of speech signal , the linear prediction coding , vector quantization , lbg arithmetic and perceptual weighted filtering
第二章着重讨论了g 729语音压缩协议中所涉及到的语音编码基础理论。主要包括语音信号产生的数字模型、语音信号的线性预测分析、矢量量化及其lbg算法和感知加权滤波器。 - Three optimization methods are presented by researching the algebraic codebook excitation linear prediction ( acelp ) algorithm , and optimized the feel weighted filter , the search algorithm of the linear spectrum pair ( lsp ) , and the search method of the algebraic codebook respectively
通过研究tetra数字集群通信系统中的acelp语音编解码算法,分别在感觉加权滤波器的设计、线谱对参数量化的搜索方式、代数码本的搜索方式等三个方面提出了优化算法。 - Secondly : i choose a non - linear filter named hybrid filter which combines linear and nonlinear filters is proposed for print gray image , it performs better than average fil ters and median filters on noise reduction . while retaining edges of an image . i suggest a modified version and fast implementation of this filter improve its performance . because of its reduced computation complexity , this filter excels in real - time tasks
因为噪声时常包含非线性问题，针对这种情况，既要抑制噪声，又要保护图像边缘，本文采用一从度指纹图像上噪处理研究种基于线性，非线性的混合滤波器算法，该算法比均值滤彼器，中值加权滤波器，格形滤波器，具有更好的抑制噪声的能力，不但较好的保持图像地边缘，而且能反映图像的几何结构和细节特性。 - The quantized lp coefficients are replaced by the unquantized lp coefficients in the frequency domain expression of the feel weighted filter . the error signal has more similar envelope shape , and the hearing effect is better than before because the unquantized lp coefficients have more accuracy than quantized lp coefficients
由于未量化的线性预测系数具有更高的精度,因此,误差信号通过修正后的感觉加权滤波器以后,具有与语音信号谱更加相似的包络形状,从而更好地利用共振峰对误差的掩蔽效应,达到更佳的主观听觉效果。
