Wrapped phase maps obtained using interferometric speckle techniques are often corrupted with high-frequency noise, typically due to speckle decorrelation (Aebischer and Waldner, 1999). Image processing using a low-pass averaging filter is often used to reduce the noise content. A low-pass filter kernel typically takes the form

Jun 2, 2014 The approach involves decorrelating both the original and filtered data by joint diagonalization of their covariance matrices. We trace its origins;

164–167. 3) Local Decorrelation for Improved Pedestrian Detection Woonhyun Nam StradVision, Inc. woonhyun.nam@stradvision.com Piotr Dollar´ Microsoft Research pdollar@microsoft.com Joon Hee Han POSTECH, Republic of Korea joonhan@postech.ac.kr Abstract Even with the advent of more sophisticated, data-hungry methods, boosted deci- correlation techniques are reviewed and compared. The idea behind signal decorrelation techniques is to introduce nonlinearity into each channel. This can be done by using half-wave rectifiers or time varying all-pass filters.Three methods were developed to reduce correlation between stereo signals. An audio signal processing method and apparatus for adaptively adjusting a decorrelator. The method comprises obtaining a control parameter and calculating mean and variation of the control parameter.

LMS coupled adaptive prediction and system identification: a … 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 … Wrapped phase maps obtained using interferometric speckle techniques are often corrupted with high-frequency noise, typically due to speckle decorrelation (Aebischer and Waldner, 1999). Image processing using a low-pass averaging filter is often used to reduce the noise content. 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.

Figure 2. This structure is very simple and so the objective function has been decreased. Any orthonormal filter bank with nonoverlapping analysis filters satisfies total decorrelation.

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. An automatically estimated spatial reliability map restricts the correlation ﬁlter to the parts suitable for tracking (top) improving the search range and performance for irregularly shaped objects.

When correcting spatial decorrelation using this equa- tion, we need to make sure that no bandpass filtering is done during the processing. The temporal

(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.

Proceedings of the 19th International Conference on Digital Audio S2a) retains GRACE mass rates (with only the decorrelation filter applied).

Correlation filter matching can be reduced to a hashtable lookup, which aggregates the complexity of the set of defined correlation filters to O(1). Constructors What does decorrelated mean? Simple past tense and past participle of decorrelate.

Filter based trackers model the appearance of objects us-ing ﬁlters trained on example images. 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

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.

Channel reliability weights calculated in As the chosen approach identifies non-stationary parts of the time-series and outliers, the decorrelation filters are estimated from clean data only.
