Abstract
Multiple object localization and recognition has been an important problem in recent years not only because of its difficulty to be time efficient but also due to many different schemes of widespread applications. In many previous works, only a limited amount of object models contribute to less computational time. However, they tend to not work efficiently together with large-scale database. In this paper, we propose two search algorithm and search-based object recognition system to recognize and localize multiple objects in an image with a large-scale database. Since we tackle this problem with the idea that users can get brief information of an item immediately after taking only a snapshot, a low response time is also taken into account. Therefore, we propose a new spatial verification algorithm to improve the speed of localizing objects. We implement the algorithms within a large-scale book recognition system and present experimental results that demonstrate the efficiency of our algorithms in terms of detection recall, precision, and speed compared to the baseline and efficient subwindow search (ESS) approaches.
