To incorporate the georegistration and restoration processes into airborne data processing in support of U.S. Department of Energy's nuclear emergency response task, we developed an adaptive restoration filter for airborne Daedalus AADS1268 ATM thermal data based on the Wiener filtering theory. Preliminary assessment shows that this filter enhances the detectability of small weak thermal anomal...

Digital color cameras using a single detector array with a Bayer color filter array (CFA) require interpolation or demosaicing to estimate missing color information and provide full-color images. However, demosaicing does not specifically address fundamental undersampling and aliasing inherent in typical camera designs. Fast non-uniform interpolation based super-resolution (SR) is an attractive...

Denoising multidimensional NMR-spectra is a fundamental step in NMR protein structure determination. The state-of-the-art method uses wavelet-denoising, which may suffer when applied to non-stationary signals affected by Gaussian-white-noise mixed with strong impulsive artifacts, like those in multi-dimensional NMR-spectra. Regrettably, Wavelet's performance depends on a combinatorial search of...

When a conventional NLMS adaptive filter is used to predict a process, especially when predicting several samples ahead, non-linear effects can be observed. These non-linear effects produce adaptive filter performance that exceeds that of the conventional Wiener filter, and engenders weight behavior that is of a time-varying nature. After showing the existence of such non-linear effects, we sho...

In the field of artificial intelligence, Adaptive Learning Technique refers to the combination of artificial neural networks. In this research paper the Adaptive Learning Technique has been implemented to carry out the Detection and Localization of Sound (S). In this technique two methods are used to detect the pure sound, In the first method wiener filter are used to reduce the amount of noise...

we propose an accurate subpixel shift estimation method for the registration of noisy images. The proposed method uses a specific local region to perform phase correlation instead of the whole noisy image and applies an adaptive Wiener filter to a local region for suppressing noises. Firstly, a local region is selected in the vicinity of the feature points from Harris corner detection by analyz...

4.35k1.86 15.48f3.21 Abstract Previous research showed that whitening the surface electromyogram (EMC) can improve EMG amplitude estimation. However, conventional linear-filter whitening fails at low EMG amplitude levels, perhaps due to additive background noise in the measured EMG signal. This paper describes an adaptive whitening technique, effective at low EMG levels, that cascades a non-ada...
