Symmetry-driven shape description for image retrieval

作者：

Highlights：

• We use rotation and reflection symmetries for structural shape description.

• The posterior shape similarity enhances the shape matching performance.

• Test results on public dataset show increased retrieval accuracy.

• Any other previous or future shape representation can be combined with our method.
