According to principle of fair comparison: (1) corresponding initialization parameters are same set in these algorithms as Table 3 shows,the settings are according to [2]; (2) using same starting searching points to initialize the colony, as shown in Table 4 and Appendix.
We start with the idea of Subsection 3.1, using the diameter of an MST of a randomly selected set of points to initialize all the control points of a backbone curve, and then develop the iterative procedure below that refines the control points to be equidistant from the left and right boundaries.
Use linear interpolation between the measured points in to initialize.
In particular, we use the mean and standard deviation of the data points in each class to initialize Ω and the ratio of data points in different classes to initialize α i.
The approach of using MDS and dimensionality reduction to initialize points is named as MDSInit, while RandInit denotes the use of multiple sets of random initial points.
For Bayesian network generation, the interaction matrix between each node for each time point was learned and then used to initialize the inference process for the next time point.
The segmentation of MC consists of two steps: firstly, several edge points are detected and used to initialize the MC segmentation, and then an active contour is used to refine the initial segmentation.
We use the shortest path P obtained in the graph-step to initialize the control point locations { C k, k=1,…, K} of the deformable curve C, which is further refined and smoothed using a local search.
We first simulate the system with nominal parameters K0 and choose a point on the corresponding periodic orbit to initialize the Newton iterations to calculate x e (K0).
Within a box bounding the face, a pictorial structure model was used to identify 9 central facial feature points (Everingham et al., 2009), which then were used to initialize the placement of an additional 27 feature points.
