Keypoint descriptor matching with context-based orientation estimation

作者:

Highlights:

• Novel matching strategies for histogram-based descriptors are presented.

• Global dominant orientation is used by exploiting the image context.

• A new 3D extensible framework to evaluate feature descriptors is introduced.

• 2D/3D comparisons with state-of-the-art rotational invariant descriptors are reported.

• Results show the effectiveness of the proposed matching approaches.
