Analysis of Using Metric Access Methods for Visual Search of Objects in Video Databases
2014
Revista de Informática Teórica e Aplicada
Preserved Fulltext
Though works in the literature have only adopted a simple sequential scan during search, we investigate the use of different metric access methods (MAM): M-tree, Slim-tree, and D-index, in order to accelerate ...
Vector quantizing these region descriptors provides a visual analogy of a word -a visual word. ...

This article gives a survey for bag-of-words (BoW) or bag-of-features model in image retrieval system. ...
A common way to achieve this is first quantizing local descriptors into visual words, and then applying scalable textual indexing and retrieval schemes. ...
We then sequentially discuss the key point detection, local description, vocabulary generation, vector quantization, indexing and search. ...
