Sentence examples for deviations of noise from inspiring English sources

The standard deviations of noise in the first tow IMFs are estimated by a robust estimator, and then the noise variances in other IMFs can be obtained after the variance relation among the IMFs decomposed from fGn is derived.

In this case, the estimated standard deviations of noise for "Orbit" and "Interview" sequences are 10.01 and 10.47, respectively.

The standard deviation of noise is σ=35.

The standard deviation of noise is set to be 0.001. 1) Estimation accuracy test  .

At the mean while, the standard deviation of noise must be pre-estimated.

where σ is the standard deviation of noise which is assumed to be known.

The experimental results demonstrate that the proposed algorithm performs well when the standard deviation of noise is not very high.

With the standard deviation of noise decreasing, all the maximum deviations approach to zero, implying that the estimate values approach to the true states.

To fix this threshold in SNR, detectability (defined as the ratio of peak spectral density and standard deviation of noise) is calculated.

Figures 10(a)–10(f) display the results for the noisy "Lena" image when the standard deviation of noise is 40.

(2) Do not need to estimate the standard deviation of noise before image de-noising, which will avoid the error existed between estimated value and real value and reduce the complexity of the algorithm.  .
