Figure 1From: Robust and Accurate Curvature Estimation Using Adaptive Line Integrals(a) For a point (the black square dot) on a curve (the gray line), we draw a circle centered at that point. The integral region is denoted by red dashed line. It is convenient to write the equation of the curve, in the neighborhood of , using and as a coordinate frame. (b) After obtaining and , the line integrals can be easily computed. It does not matter which coordinate system we use for computing and . One can always obtain a curvature estimate by performing eigenvalue decomposition.Back to article page
