(f) ; (2) until both is smaller than a threshold, where the index denotes the th iteration. .
Then the points whose distance is smaller than a threshold are kept.
We require that these errors have to be smaller than a threshold (varepsilon ^{0}).
If the area of a region is smaller than a threshold, this region is removed.
This often means λ should be smaller than a threshold value.
After the first iteration, we select all arcs whose error curvature ϕs are smaller than a threshold (hat {phi }).
Such connectivity is related to the fraction of grain boundaries (GBs) with misorientations smaller than a threshold value (fθ < θth) as well as to their local arrangement.
Using a piecewise linear function, time slots with a rate smaller than a threshold can get negative, those larger than a threshold can have positive weight.
The soft-thresholding filter is used to put to zero all the wavelet coefficients with the absolute value smaller than a threshold.
The above search process is iterated until the difference between the two found points of the successive searches is smaller than a threshold.
A point is considered to be a valid solution after iterating if its cost from Eq. (34) is smaller than a threshold.
