Figure 3From: IDSS: deformation invariant signatures for molecular shape comparisonIllustration of definition of the inner distance. The red dashed lines denote shortest paths within the shape boundary surface that connect two landmark points x and y. The right object B is articulated deformation to the left one A, and the relative change of the inner distances between the corresponding pair of points (e.g. x and y) during articulated deformation are small.Back to article page
