This is accomplished through the development of a convergent stochastic approximation form of estimator for the common variance value.
The motor skills were evaluated by using the reproducibility of muscle activation patterns, which were represented by using the variance value of the Electromyographic (EMG) signal patterns, and the motion accuracy.
The horizontal blue lines both in c,d indicate the highest 31-year averaged interannual variance value of the time series, centred on 1992 AD. The positive correlation between Taiwan tree δ18O and the boreal spring NIÑO3.4 index reflects drier conditions across the western Pacific region during El Niño events.
In conventional performance-adaptive methods, control systems are designed such that the variance of the control error is less than or equal to a specified value and the variance of the differences in the control input is minimized without changing the acceptable variance value of the control error.
On the other hand, since the design objective of the present study is to reduce energy consumption, the variance of the differences in the control input is first set, and then the variance of the control error is minimized without changing the acceptable variance value of the differences in the control input.
Compute local variance value for all pixels.
The smaller variance value, the better performance can be achieved for the reversible watermarking scheme.
Indeed, the proposed approach only depends on the noise variance value.
with choice of gaussian variance value γ tunes up the strength of the resulting weights.
So, a high variance value indicates that the sub image is not flat.
Table 2 shows the variance value for all rate-distortion points.
