Singularity Detection via Wavelet Transform Modulus Maxima
Zheng Qing-qing · Remote Sensing Information · 2006
The singularity of a signal could be depicted by the attenuation of WaveletTransform modulus as scale changes.That is,signal singularity could be detected by tracking wavelet transform modulus local maxima with fine scales.In this paper, some models and examples are given to support the above-mentioned conclusion.Even if the signal is affected by stochastic noise,the method is also efficient.
