The Flickr Multiple Object Dataset contains two dataset Flickr-M1 (bus & car) and Flickr -M2 (bus & bicycle). The Flickr dataset is composed of images downloaded with “bus & car” and “bus & bicycle” text queries, which were then filtered manually. Flickr-M1 has 196 positive images containing both bus & car, and Flickr-M2 has 209 positive images with both bus & bicycle in them. For both these datasets, we harvest negative training examples from the PASCAL VOC 2007 images containing neither of the two object categories. If you use this dataset, cite the following paper : @InProceedings{Gandhi13, author = "Gandhi, A. and Alahari, K. and Jawahar, C.~V.", title = "Decomposing Bag of Words Histograms", booktitle= "Proc. IEEE International Conference on Computer Vision", year = "2013" } The Flickr Multiple Object Dataset consists of images provided by "Flickr".
