This is a selection from the misc database, which is publicly available and has been used in the image retrieval literature. It originated with Virage (Natsev et al., 1998), and is now available from www-db.stanford.edu. This may be as close as one can get to a standard dataset for image retrieval and image classification, where traditionally each author uses his or her own home-brewn image database.
The original collection consists of approximately 10000 images, from which I selected 1172 and classified them into 14 (disjoint) classes. I also prepared folds for tenfold cross-validation; each fold consists of 117 images, except for folds 0 and 4, which contain 118 images each. Care has been taken to give each class approximately the same number of representatives in each fold (stratified cross-validation).
