Landmark Selecting on 2D Shapes for Constructing Point Distribution Model
A new method of selecting landmarks on 2D shapes which are represented by Centripetal Catmull-Rom spline is proposed in this paper.Firstly,a mean shape is generated from training set and landmarks on mean shape are extracted based on curvature and arc-length information.Then the corresponding landmarks on each shape can be obtained by projecting the mean shape back to each sample using non-rigid registration method Coherent Point Drift.Experiments showed that landmarks auto-generated are more accurate than landmarks manual annotated when used in segmentation.
