Bag of Words : Quality Issues of Near-Duplicate Image Retrieval

Paradowski M., Durak M., Broda B.

Machine Graphics and Vision

2014

Vol. 23, No. 1/2

83--96

This paper addresses the problem of large scale near-duplicate image retrieval. Issues related to visual words dictionary generation are discussed. A new spatial verification routine is proposed. It incorporates neighborhood consistency, term weighting and it is integrated into the Bhattacharyya coefficient. The proposed approach reaches almost 10% higher retrieval quality, comparing to other recently reported state-of-the-art methods.
