Abstract:

A topology-keeping active contour model was proposed and applied to optimize the piecewise linear curve in triangular meshes. The model is directly moved on the triangular meshes and no parameterization is needed, therefore, the data structure of the meshes can be easily retained and the computation cost can be reduced in the adjusting process. The topological relationship between curves can be remained unchanged by the data structure. Based on curve energy, the proposed active contour model can be applied for curves optimization in terms of curve smoothing and curve adjustment. Experiment results show that the proposed model can capture the convex/concave feature of the curves and improve the smoothness of the curves.
