This algorithm transforms the 2D points to 3D (lifted to a paraboloid by computing a z-coordinate for each pit center as z = x + y), computes the convex hull in 3D, and projects the lower part of the hull back to 2D to obtain the triangulation [36].
The "center" for each of the baseline clusters was defined by computing a mean score for each of the resulting 10 principal components at baseline by cluster.
In this work, we have employed the algorithm proposed in [23] which is based on aligning the palmprint by computing the center of mass and also by locating the valley regions.
In this experiment, we automatically set 35 light source positions for 4-D light field estimation by computing the center of saturated regions on the image with d=0m m.
In this experiment, for making the discussion simple, we first gave three light source positions for 4-D light field on (mathcal {L}) by computing three center points of saturated regions on the image shown in Fig. 5 c which is taken at the distance d=0m m.
In the well-known bottom-up attention model [10], three basic low-level features (i.e., color, intensity, and orientation) are used to generate three conspicuity maps by computing the center-surround contrast.
Then, each occupancy map from the first macrostate configuration was compared to each map of the second configuration by computing the not centered correlation coefficient.
Skeleton grows from seed, which is obtained by computing the joint cluster's center and searching the nearest branch point to the center in each branch.
Body sway was evaluated by computing the excursions of the center of pressure (CoP) measured over a period of 25.6 s; the equipment contained an Analog Digital converter of 16 bits and the sampling frequency of the CoP was 40 Hz.
In DLEP, for a given image the local extrema in 0°, 45°, 90°, and 135° directions are obtained by computing local difference between the center pixel and its neighbors as shown below: I^{prime} (g_{i} ) = I(g_{c} ) - I(g_{i} );quad i = 1,2, ldots,8 (6)The local extremes are obtained by Eq. (7).
