xxx SEISMIC DATA FILTERING WITH HIERARCHICAL LAPPED TRANSFORMS AND HIDDEN MARKOV MODELS
نویسنده
چکیده
We propose a method for uncoherent noise removal in geophysical data. The Multiple Wavelet Stacking is based on a concurrent use of wavelet-based shrinkage and data and time-scale dependent threshold choice. Since one singular wavelet does not match all the time-varying properties of a signal, the simultaneous use of several wavelets is able to lower some shrinkage shortcomings, such as wavelet dependency, and to further reduce the residual noises.

متن کاملLapped transform domain denoising using hidden Markov trees
Algorithms based on wavelet-domain hidden Markov tree (HMT) have demonstrated excellent performance for image denoising. The HMT model is able to capture image features across the scales, in contrast to classical shrinkage that thresholds subbands independently. In this work, we extend the aforementioned results to a lapped transform domain. Lapped Transforms (LT) are -channel linear phase filt...
متن کاملImage Characterization with Dft-based Complex Lapped Transform for Texture Segmentation
In this paper we generalize the lapped orthogonal transforms to include complex lter coeecients. We derive the perfect reconstruction conditions for this class of complex lapped transforms. A special discrete Fourier transform-based complex lapped transform (DCLT) is constructed which tends to provide a good mixture of locality and smoothness. In applying the DCLT to an image, a quadtree scan i...
متن کاملEvaluation of the Hidden Markov Model for Detection of P300 in EEG Signals
Introduction: Evoked potentials arisen by stimulating the brain can be utilized as a communication tool between humans and machines. Most brain-computer interface (BCI) systems use the P300 component, which is an evoked potential. In this paper, we evaluate the use of the hidden Markov model (HMM) for detection of P300. Materials and Methods: The wavelet transforms, wavelet-enhanced indepen...
متن کاملContext dependent tree based transforms for phonetic speech recognition
This paper presents a novel method for modeling phonetic context using linear context transforms. Initial investigations have shown the feasibility of synthesising context dependent models from context independent models through weighted interpolation of the peripheral states of a given hidden markov model with its adjacent model. This idea can be further extended, to maximum likelihood estimat...
