Curve Evolution

Property 2: Invariance

• Rotation: The values of the cost function are computed in the tangent space, which is a torus.
• Scaling:The curve length is normalized.
• Reflection:The mimimum of the cost function does not depend on the direction and order of the traversal of line segments.
• Translation:The tangent space only contains information about the relative positions (relative to the first vertex) of the vertices.
