Adding spatial distribution clue to aggregated vector in image retrieval

Adding spatial distribution clue to aggregated vector in image retrieval

Abstract This study proposes a novel algorithm that enhances the distinctiveness of the traditional vector of locally aggregated descriptors (VLAD) using spatial distribution clue of local features. The algorithm introduces a new method to compute the spatial distribution entropy (SDE) of clusters....
