A BoVW-based similar image Retrieval Supported by Salient Region
Zijun Zou, Hisashi Koga (UEC) PRMU2013-110 MVE2013-51
Abstract (in Japanese) (See Japanese page) 
(in English) The Bag of Visual Words(BoVW) model is prevailing in the area of image retrieval. However, because the BoVW model treats all feature points equally, the importance of the foreground which represents the semantics of an image well is ignored. This paper proposes a new BoVW-based similar image retrieval method paying attention to the similarity of the foreground. Our method assumes that the foreground location in an image can be approximated by its salient region and examines the similarity between the salient regions of two images. Specifically, we divide the given image into the foreground and the background by binarizing its saliency map and extract the foreground feature histogram from the foreground region. Finally, the similarity between a pair of images is calculated by summing up the similarity of the foreground feature histograms and that of the global feature histograms derived from the entire images. Our method is expected to improve the retrieval accuracy, since the foreground similarity is emphasized. The experiment on the Caltech-101 image database shows that the recall is surely improved by our method as compared with the conventional BoVW method.
