Fig. 4From: Effective elliptic arc selection from connected edge pointsInlier arc selection process of our method. a Used points to fit the ellipse in (b). The blue arc is the selected inlier arc. The green arcs are the extended arcs from the selected inlier arc. b Fitted ellipse. c Signed fitting residual graph. The horizontal axis shows the index of the points. The vertical axis shows the signed fitting residual. The blue and green arcs correspond to the arcs in (a) in the next rowBack to article page
