TY - JOUR ID - 949254 AU - Homola, Tomáš - Dohnal, Vlastislav - Zezula, Pavel PY - 2011 TI - Searching for Sub-images using Sequence Alignment PB - IEEE Computer Society CY - Los Alamitos, California SN - 9781457720154 KW - image matching KW - sub-image retrieval KW - local image features KW - sequence alignment N2 - The availability of various photo archives and photo sharing systems made similarity searching much more important because the photos are not usually conveniently tagged. So the photos (images) need to be searched by their content. Moreover, it is important not only to compare images with a query holistically but also to locate images that contain the query as their part. The query can be a picture of a person, building, or an abstract object and the task is to retrieve images of the query object but from a different perspective or images capturing a global scene containing the query object. This retrieval is called the sub-image searching. In this paper, we propose an algorithm for retrieving database images by their similarity to and containment of a query. The novelty of it lies in application of a sequence alignment algorithm, which is commonly used in text retrieval. This forms an orthogonal solution to currently used approaches based on inverted files. The proposed algorithm is evaluated on a real-life data set containing photographs where images of logos are searched. It was compared to a state-of-the-art method and the improvement of 20\% in average mean precision was obtained. ER -
