The first step is to obtain an approximation of the associated codimension-1 problem formulated by Ambrosio and Soner, where the squared distance from the initial curve is used as initial condition.
This review article covers the review of all the notable protection coordination methods starting from the initial curve fitting, graph theory and application of exact optimization tools for solving the protection coordination problem for radial/interconnected power systems.
In GrabCut, the energy minimization scheme works iteratively, which updates k and θ by current segmentation and uses new k and θ to obtain new segmentation by solving the problem in Equation 2. The algorithm starts from an initial curve setting manually.
Estimating the left ventricular wall thickness in each time frame by finding the mean distance from the initial curve to the right ventricular blood pool.
These will typically vary, indicating deviations from the idealized geometry of the initial curve.
Figure 7 shows the three relative permeability curves include: target curve, initial curve, and optimized curve.
From Figure 4, we can see that the proposed method can achieve successful segmentation in these image pairs with various initial curve settings, which demonstrates that the proposed model is robust to the initial curve setting.
From the thresholded binary image, we constructed initial curves of the BML boundaries and then a region-based curve evolution method [ 20] refined the initial curves to obtain an accurate BML border.
In such cases, the system changes the estimated pattern from the initial middle curve to a more appropriate one if the deviation exceeds five minutes.
Analyzing the case of a sinusoidal crimp that has been proposed in (3.3), we proceed from the initial fiber curve (tilde{mathbf{r}}^{mathbf{0}} tilde{s})={tilde{s}}mathbf{e}_{mathbf{1}}+ c sin (mathrm{C} pitilde{s} mathbf{e}_{mathbf{2}}), (tilde{s} in[0,l]) with crimped length l, crimp number (mathrm{C}inmathbb{N}_{0}) (bows per unit length) and amplitude (cgeq0).
