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.

Simple past tense and past participle of decorrelate. (verb) 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. 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).

The temporal FILTRODISC depth filtration modules are used in a sealed DISCSTAR™ housing and were enable large filter areas to be handled easily.

Initially, the work investigates the suitability of a method of signal decorrelation termed diffuse signal processing (DiSP), which utilises FIR decorrelation filters termed temporally diffuse

A low-pass filter kernel typically takes the form The DDK decorrelation filter serves as main benchmark for the assessment of the VADER filter. For comparable filter strengths the VADER filters achieve a better de-striping and deliver smaller formal errors than static filters like the DDK. Decorrelation methods seek to maximise the randomness of the phse between the two signals. This can be acheived using two mechanisms, phase based and amplitude based.

For RLS the dimension of the decorrelation matrix is equal to the filter length. For large filters this implies a high complexity.

In the studio, effects processors -reverb, delay, chorus, flanger, comb filter, etc. – produce decorrelated output. An alternative to the state-of-the-art approach of adjusting decorrelation filters to outlier-free parts of a segment is investigated. A robust approach is used to estimate the decorrelation filter coefficients.

The delay ∂ = 10ms (440 samples is experiment chosen to produce stereo sounds for the application concerned. 5.L HRTF MEASUREMENT The ability of humans to use spatial cues to estimate the spatial location of a target is of great practical and research importance.Recently, In nature decorrelation is a product of the delay, reverberation and filtering properties of any room or space. In the studio, effects processors -reverb, delay, chorus, flanger, comb filter, etc. – produce decorrelated output. The default settings used attempt to maximise the amount of decorrelation between loudspeakers by randomly panning transinets to different loudspeakers and using optimal filters for the steady-state components (that can be longer as there is less risk of transinet smearing).

The decorrelation process may involve using a GOCE satellite gravity gradiometry (SGG) data are strongly autocorrelated within the various tensor components.

2020-01-01 · In , Choi considered a dynamic recurrent network (IIR filter) for the task of spatio-temporal decorrelation: (5) y (k) = x (k) + ∑ p = 0 L W p (k) y (k − p) where W p (k) ∈ R n × n, 0 ≤ p ≤ L denote the weight matrices, and L is the order of filter.

The target is ini-tially selected based on a small tracking window cen-tered on the object in the ﬁrst frame. From this point on, tracking and ﬁlter training work together. The target is tracked by correlating the ﬁlter over a search window in US9830916B2 US14/766,371 US201414766371A US9830916B2 US 9830916 B2 US9830916 B2 US 9830916B2 US 201414766371 A US201414766371 A US 201414766371A US 9830916 B2 US9830916 B2 US 9830 Using filter cells to eliminate wavelengths associated with interfering gases is called positive filtering in the field of spectroscopy. You may think of this as filtering out all the wavelengths the instrument should not “care about.” In order for positive filtering to be completely effective, the analyzer must filter out The current paper presents a method to generate decorrelation filters for three - dimensional loudspeaker arrays with arbitrary angular spacing as well as for binaural configurations.

decorrelation filter subtracts the effect of channel distortion in the log-spectral domain and normalizes an unknown channel from the viewpoint of the linear-spectral domain. Fig. 1. Block diagram performing blind decorrelation based on an information-maximization approach. Blind decorrelation filtering (W) Activation function It is commonly known that speckle decorrelation limits the possibility to measure large deformations by electronic speckle pattern interferometry (ESPI). We present here a method to lift this limitation and show that ESPI can now be used to measure large deformations, even in a hostile environment.

Decorrelation of audio signals is a critical step for spatial sound reproduction on multichannel configurations.
