摘要：

This paper presents a novel method for retrieving different instances of a region or object of interest in a video database. We propose three dynamic region construction and matching algorithms aiming at obtaining the most similar instance of the query model from each candidate image. The first two involve a greedy, dynamic region construction method. The third is based on simulated annealing, and aims at determining a global optimum. An interactive selection mechanism allows the user to select an object directly from the video and to start a query using as input this information in order to access visually similar content. Experimental results show promising performances, with object detection rates of up to 81%.
