Sentence examples for by estimating the gradient from inspiring English sources

A basic approach for editing process is to minimize the variation of the image f over the region Γ by estimating the gradient norm ||∇f||, which is also known as Tihkonov regularization [13]: min f : Γ → R E f = ∫ Γ ∇ f 2 f ∂ Γ = f * ∂ Γ (1).

Our method works by estimating the gradient of the likelihood function first, and then searching for an optimal solution by iteratively updating the parameters along the gradient descent direction.

For the DHT, the transform is obtained by estimating the gradients at a single scale σ=1.5.

However, it is possible to compute a priori values for the gradients with external data from, e.g., numerical weather models or by estimating the gradients using observations from co-located GNSS sites.

The severity of coarctation can be assessed by measuring the volume of collateral flow present, or by estimating the pressure gradient across the stenosis.

RV systolic pressure was calculated by estimating the systolic pressure gradient across the tricuspid valve using the modified Bernoulli equation [16, 17] and adding this value to the right atrial (RA) pressure.

RV systolic pressure was calculated by estimating the systolic pressure gradient across the tricuspid valve using the modified Bernoulli equation [ 16, 17] and adding this value to the right atrial (RA) pressure.

PA pressures may be assessed by estimating the systolic-pressure gradient across the tricuspid valve by using the modified Bernoulli equation [ 9, 66, 67], and although the correlation between invasive and sonographic measurement has been shown to be excellent in these studies, no studies have correlated PAC with echocardiographic measurements in the ICU population.

This approximation is obtained by estimating the exponential summation in the gradient with only some carefully chosen dominant terms.

In the narrowest sense, by estimating the mutual information distance in the gradient spectra, we show that the fluctuation pattern of the short and weak 3 GHz impulsive solar burst, with energetic amplitudes <350 SFU, is closer to the intermittent and strong MHD turbulent variability pattern.

The agents know their position and the local value of the field, and by communicating with their neighbors estimate the gradient direction of the field.
