Before revision:  A key ingredient in our model is the construction of Finsler geodesic metrics, which are capable of integrating anisotropic and asymmetric edge features,  region-based homogeneity  and/or curvature regularization.
After revision:  A key ingredient in our model is the construction of local geodesic metrics, which are capable of integrating anisotropic and asymmetric edge features, region-based homogeneity and/or curvature regularization.
