| Abstract: | Singular point features are analyzed for singulax signals throgh wavelet analysis, and wavlet singular detection is applied to wavelet filtering to realize time-frequency two-dimension filtering. So that the singular point information is kept while the noise is filtered. |
| Keywords: | Wavelet transformation time-frequency local feature local maximum wavelet singularity detection wavelet filtering time-frequency two dimension filtering |
