| Abstract(in English) | In this paper we first explain our retrieval approach for the specific object search task based on image queries. We then propose a methodology to effectively utilize the region-of-interest (ROI) information that is supposed to also input to the search system. Our proposed method is a search result re-ranking and the top K results in the initial search result ranking ordered by using image features within the ROI are re-ranked by using image features outside the ROI. This new approach is expected to alleviate a topic drift induced by the background information in the image query and to contribute for the improvement in the search accuracy compared with the standard approach that utilizes the background information simultaneously with the specific object information. The experimental evaluation using the TRECVID instance search task dataset shows the ameliorated search precision. |
