Prewhitening for Narrow-Band Noise in Subspace Methods for Noise Reduction
A fundamental issue in connection with subspace methods for noise reduction is that the covariance matrix for the noise is required to have full rank, in order for the prewhitening step to be defined. However, there are important cases where this requirement is not fulfilled, typically when the noise has narrow-band characteristics, including the case of tonal noise. We extend the concept of pr...
متن کاملCircular Mean Filtering For Textures Noise Reduction
In this paper, a special preprocessing operations (filter) is proposed to decrease the effects of noise of textures. This filter using average of circular neighbor points (Cmean) to reduce noise effect. Comparing this filter with other average filters such as square mean filter and square median filter indicates that it provides more noise reduction and increases the classification accuracy...
متن کاملA Novel Noise Reduction Method Based on Subspace Division
This article presents a new subspace-based technique for reducing the noise of signals in time-series. In the proposed approach, the signal is initially represented as a data matrix. Then using Singular Value Decomposition (SVD), noisy data matrix is divided into signal subspace and noise subspace. In this subspace division, each derivative of the singular values with respect to rank order is u...

متن کاملAn Adaptive Subspace Filter for Noise Reduction
In this paper, we present a novel structure for adap-tive noise ltering based on subspace methods. Our approach requires no eigenvalue or singular value decomposition to obtain the principal signal components. In addition, only the noisy signal, and no reference signal is needed. A modiied RLS adaptive algorithm is proposed which approximately performs the principal component analysis of the no...
