Image Retrieval for Online Browsing in Large Image Collections
Original language description
Two new methods for large scale image retrieval are proposed, showing that the classical ranking of images based on similarity addresses only one of possible user requirements. The novel retrieval methods add zoom-in and zoom-out capabilities and answerthe 'What is this?' and 'Where is this?' questions. The functionality is obtained by modifying the scoring and ranking functions of a standard bag-of-words image retrieval pipeline. We show the importance of the DAAT scoring and query expansion for recall of zoomed images. The proposed methods were tested on a standard large annotated image dataset together with images of Sagrada Familia and 100000 image confusers downloaded from Flickr. For completeness, we present in detail components of image retrieval pipelines in state-of-the-art systems. Finally, open problems related to zoom-in and zoom-out queries are discussed.
