We present a new method for content-based image retrieval (CBIR). Region-based approach would be effective to tackle with various kinds of fluctuation such as scale, viewpoint, and foreground-background changes. Many algorithms to extract interest points or regions have been proposed for removing such fluctuations. In this report, we propose a new concept of CBIR. The proposed method utilizes saliency for weighting, not for extracting interest regions. That is, interest points are weighted by neighboring saliency. Saliency-weighted sililarity measure is used for feature matching. One of the problems in the proposed framework is that applying weighted similarity to existing indexing methods is difficult. We also propose a new indexing method called two-stage index search. The first stage is based on saliency and the second one is based on (non-weighted) similarity. Two-stage index search enables us to quickly detect all point features such that saliency-weighted similariry value exceeds a predefined threshold. |
