Fast Interactive Object Annotation with Curve-GCN

Appendix

In the supplementary material, we provide additional qualitative and quantitative results for our Curve-GCN model. We compare models with different number of control points, to indicate the best effective topology. We further provide human-in-the-loop experiments for Polygon-GCN. Additional qualitative examples for both the automatic and interactive modes are given. Furthermore, we build a annotation tool and show several real human annotation examples.
