A convex hull around the remaining inliers forms up the conflict area. Drive-line modeling extracts the drive lines from consecutive lines in each approach. In this step, the road surface mask is used to filter drive lines which are not on road surface, such as those which would be ...
We extract tip position of the index finger from the hand segmentation result by convex hull analysis. The video was recorded by a subject wearing the head-mounted Logitech camera in the indoor scene at a resolution of 640 × 480 and a speed of 30 FPS. The test video totally contains...
The convex hull-based method first segments the pelvis into regions such as the ilium and pubis, and then defines the anterior pelvic plane (APP) using the faces of the pelvic convex hull and the vertices with the shortest distances to the ilium and pubis regions. However, this method is ...
2D object (green) and background (red) markers required for marker-controlled watershed transform Full size image To obtain the background marker, for each slice including the kidney, a rectangular convex hull is applied. Moreover, to increase the kidney region a morphological dilation with a me...

According to the properties of the convex hull, any extreme point of the convex hull in the point set is the boundary point of the point set, and it is set as the initial point of the boundary. (3) Obtain the boundary point set of the entire point cloud. Determine whether the ...
Finally, the contour, 𝐺𝑉4GV4, of the cluster is calculated from a convex hull, which is the smallest convex set that contains the points. The density, 𝐺𝑉5,GV5, is the number of points of the cluster, 𝐶𝑓Cf for a volume 𝑉𝑓Vf. 4. Numerical Investigation 4.1. Simu...
convex hullGraphics Processing Unit (GPU)parallel algorithmAn effective strategy for accelerating the calculation of convex hulls is to filter the input points by discarding interior points. In this paper, we present such a straightforward preprocessing approach by discarding the points locating in a ...
