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. 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).

The proposed non-linear processing combines a shaped comb-allpass (SCAL) filter with the injection of psychoacoustically masked noise. We show that the

Digital allpass ﬁlters contain poles inside the unit circle matched with zeros at reciprocal magnitudes and at the same fre- quencies as the pole. The decorrelation filters are forward predictor error filters with their coefficients being matched with the correlat ion properties of the speech signal [17]. decorrelation filtering is applied before the Slow Feature Analysis to get accurate separation.

We show how to numerically obtain such a decorrelation filter by solving a nonlinear optimization problem. This technique can also be applied to other linear separation methods, whose output signals are decorrelated, such as ICA. Published in: 2011 International Conference on Computer Vision.

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. This technique can also be applied to other linear separation methods, whose output signals are decorrelated, such as ICA. Published in: 2011 International Conference on Computer Vision.

In this, we will remove all the featu Not only will correlation filters be optimized at declaration time, but they will also be optimized at runtime. Correlation filter matching can be reduced to a hashtable lookup, which aggregates the complexity of the set of defined correlation filters to O(1).

One of the most popular filters is a two-step filter: (1) decorrelation filter and (2) Gauss filter. Both filters must be adapted to the noise level of the data. While the Gauss filter only depends on one parameter, the decorrelation filter depends on several parameters producing multiple combinations.

We refer to this decorrelation as blind noise decorrelation. 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.

A camera lens filter may mount in front of the camera or screw onto the lens, and is used to change the amount of light that enters the image sensor. Here's everything you need to know. A camera lens filter is an additional piece of glass (
