Curvilinear Structure Tracking Based on Dynamic Curvature-penalized Geodesics

作者：

Highlights：

• We present a dynamic curvature-penalized geodesic model in the orientation-lifted space to detect weak structures with complicated geometries.

• Path features are designed to introduce the slow-varying constraint into the curvaturepenalized geodesic model based on a local geodesic backtracked scheme in the orientationlifted space.

• The local bending operator is constructed to provide a quantitative measure of the geodesic evolving direction.

• The coherence penalty is established to guarantee the consistency of the local appearance features.
