Topic: Decorrelating and then Whitening data Extra notes for MAS622J/1.126J by Rosalind W. Picard 1. Let x be a vector of zero-mean data. Form its covariance matrix,

and coherence decreases, until it finally vanishes. The spatial decorrelation can be removed by a process recognized as range filtering, at the cost of decreased

Decorrelation filter

Decorrelation of audio signals is a critical step for spatial sound reproduction on multichannel configurations. Correlated signals yield a focused phantom source between the reproduction loudspeakers and may produce undesirable comb-filtering artifacts when the signal reaches the listener with small phase differences.

DStretch is a tool for rock art researchers who wish to enhance images of pictographs. It is a plugin to ImageJ. ImageJ is an image processing and analysis program written in Java. It needs to be installed first before you can use DStretch.

decorrelation filtering is applied before the Slow Feature Analysis to get accurate separation. In this paper the image separation is performed with the following steps. First we use a linear filter to decorrelate the sources and their derivatives in the mixtures. Then apply Regularized sparse kernel SFA to the filtered mixtures for We show how to numerically obtain such a decorrelation filter by solving a nonlinear optimization problem.

correlated) and filters them out. The output table will contain the reduced set of columns. 2019-08-06 · Therefore, we design two different decorrelation filters that preprocess the training data for discriminative learning. The first one is a linear whitening filter combined with the principal component analysis (PCA), which forces the covariance matrix of different feature dimensions to be identity. Audio Engineering Society Audio Signal Decorrelation Based on Reciprocal-Maximal Length Sequence Filters and Its Applications to Spatial Sound Bo-sun Xie 1, Bei Shi 1, and Ning Xiang 2 * 1 Acoustic Lab, School of Science, Physics Dept., South China University of Technology, Guangzhou, 510641, China phbsxie@scut.edu.cn 2 Graduate Program in Architectural Acoustics, School of Architecture In this study the feasibility and performance of time variable decorrelation (VADER) filters derived from covariance information on decadal Gravity Recovery and Climate Experiment (GRACE) time series are investigated.

sound technology making use of decorrelation filters to provide an impact on the spatial imagery. Virtual Surround Sound system makes it possible to reproduce multi channel recording over an ordinary pair of stereo headphones. In the field of spatial hearing, signal decorrelation is known to have a dramatic impact on the In general, the de-correlation filtering can be a linear process (such as linear spectrum shaping or linear prediction filtering, LP) or a non-linear process (such as linear prediction coding, LPC). Figure 2 illustrates signal de-correlation for a pair of signals x1(t) and x2(t). Figure 2: De-correlation filters for signal x1(t) and x2(t) ALLPASS FILTERS FOR DECORRELATION Allpass ﬁlters are useful for signal decorrelation because they main- tain a ﬂat frequency response while effecting the phrase and group delay.

Translations in context of "decorrelation filters" in English-French from Reverso Context: the arrangement may provide improved echo-cancellation for scenarios wherein the rendering of sound from the audio sources is time varying, such as when time varying decorrelation filters are used. The decorrelation process may involve applying a decorrelation filter to a portion of the received audio data to produce filtered audio data. The decorrelation process may involve using a GOCE satellite gravity gradiometry (SGG) data are strongly autocorrelated within the various tensor components. Consideration of these correlations in the least-squares adjustment for gravity field Filter responses Channel weights = Channel weights Figure 1: Overview of the proposed CSR-DCF approach.

Ratio of the variation and mean of the control parameter is calculated, and a decorrelation parameter is calculated based on the said ratio.

Correlation between installed reinforcement and RMR rating. Filter width 125 pm. Decorrelation is a general term for any process that is used to reduce autocorrelation within a signal, or cross-correlation within a set of signals, while preserving other aspects of the signal. A frequently used method of decorrelation is the use of a matched linear filter to reduce the autocorrelation of a signal as far as possible.
