Large-Scale Image Retrieval with Attentive Deep Local Features
[article]
2018
arXiv
pre-print
Preserved Fulltext

We propose an attentive local feature descriptor suitable for large-scale image retrieval, referred to as DELF (DEep Local Feature). ...
To identify semantically useful local features for image retrieval, we also propose an attention mechanism for keypoint selection, which shares most network layers with the descriptor. ...
