daubechies wavelet meaning in Chinese
多贝西小波
Examples
- And a simulation result also is shown . so , the four daubechies wavelet base is chosen to decompose images
最后通过仿真结果数据选择了daubechies4阶小波基对图象进行四级分解。 - In solving differential equations , we must increase supported assemble length since the continuity of daubechies wavelet derivative increases as supported assemble increase , that results in calculation complexly
由于daubechies小波本身导数的连续性随着支集的增加而增大，解高阶微分方程时，就必须增加支集的长度，这会使计算复杂化。 - Finally , a factual image compression method based on wavelet transform is offered . the main work is listed as follows : 1 ) in this part , the orthogonal daubechies wavelet bases from 1 to 4 are analyzed
本文所作主要工作具体如下： 1 )按照小波基的选取原则，通过对性能优良的daubechies的1到4阶正交小波基的验证，得到了实际的仿真结果数据。 - According to the characteristic of the wavelet analysis , a feasibility study is carried out on the basis of using the wavelet transform to process the actual collected signals with daubechies wavelet , and the ae signals are divided
根据小波分析的特点，本文对小波变换用于实际信号处理进行了可行性研究，选择debauchies小波对采集的数据信号进行小波变换，提取声发射信号。 - Based on the broad applications of wavelet theory in failure diagnosis , the daubechies wavelet function is employed in this system . this proposed analysis method is about to replace the traditional method with experienced operators in detecting the quality of final drive
根据对这两部分信号的分析可以判断主减速器是否有故障存在,并可进一步根据细节分解信号的周期等特性来推断可能产生故障的部位。
