Flickr Retriever -- Fast Retrieval of Flickr Photos

With image repositories growing at an exponential rate, efficient methods for querying such databases are highly sought after. In this demo paper, we present Flickr Retriever, a software program that performs fast retrieval of images from the photo sharing site Flickr using content-based image retrieval concepts. Our methods allows retrieval of JPEG compressed images using only information stored in the header of the files. In particular, we make use of the Huffman tables in the JPEG headers and the fact that during photo upload Flickr optimises these Huffman tables in an image adaptive way. Flickr Retriever can be downloaded from our website.
