α-shapes for local feature detection

作者：

Highlights：

• A novel edge sampling scheme is proposed that exploits local shape.

• Anisotropically weighted alpha shapes are introduced.

• Distinctive local features are selected from the alpha filtration.

• Competitive results are obtained for image matching and retrieval.
