energy operator
Examples
- Speech enhancement based on hilbert - huang transform theory
能量算子和频率弯折小波变换的语音识别特征参数 - Then the research of algorithms of texture - based image retrieval is devised from the following three aspects : 1 . texture - based image retrieval algorithms in spatial domain : perceptual - based tamura texture feature is analyzed ; run - length texture analyzing algorithm is improved ; four laws " texture operators which perform better in texture analyzing are achieved
空间域纹理分析方法方面，分析了对应于人眼视觉感受的tamura纹理特征，将游程长度纹理分析算法改进为游程累加的纹理检索算法；总结出在基于纹理特征的图象检索中四个有效的laws纹理能量算子。 - The paper involves two parts of closed - set text - independent speaker identification systems in noise . firstly , the paper introduces shortcomings of the parameters , such as lpcc , mfcc etc . so sub - band energy cepstral feature parameters based on multi - rate sub - band processing and teager energy operator are described . while the paper discusses the use of rayleigh cepstral liftering to weigh sub - band cepstral coefficients so as to emphasize speaker personality information
首先本文介绍了各种特征提取的方法，如lpcc 、 mfcc等，在分析了它们的缺点的基础上，本文根据人耳频率子带独立识别的特性和能量算子，提出了子带能量倒谱特征参数，并用提出的瑞利倒谱提升进行加权，突出说话人的个性信息。
