Visual query expansion with or without geometry: Refining local descriptors by feature aggregation

作者:

Highlights:

• Novel query expansion method aligned with Hamming Embedding which individually matches features.

• Refinement of local description instead of global one in the previous query expansion methods.

• Descriptor aggregation providing more compact and more robust local representation.

• No need for spatial matching to identify good candidates for query expansion.
