transform techniques for efficient watermark de-noising and extraction. However, in the recent past the evolutionary computing …

matrix obtained from market data has the noise. Here we apply the de-noising processing based on the wavelet analysis to the … properties, i.e. symmetry and ones of all diagonal elements, of the correlation matrix preserve via the de-noising processing and … the efficiency of the de-nosing processing by numerical experiments. We propose that the de-noising processing is one of …

method of prediction systems, the various signal preprocessing methods including the appropriate de-noising methods and … systems showed that the appropriate de-noising methods and the tendency of wavelet transformation had less effect on the delay … time (τ) and embedding dimension (m). The de-noising methods may ignore the detail information of the soil water signal …

the CWT de-noising process, the Morlet wavelet, whose shape is similar to mechanical shock signals, is chosen to perform …

Wavelet Shrinkage using DWT has been widely used in de-noising although DWT has a translation variance problem. In this … invariant de-noising. Experimental results show that our method, when applied to ECG data, the medical image and the textile … surface inspection can obtain better de-noising results than that of conventional Wavelet Shrinkage. …
