Stanford I2V: a news video dataset for query-by-image experiments
Proceedings of the 6th ACM Multimedia Systems Conference(2015)
摘要
Reproducible research in the area of visual search depends on the availability of large annotated datasets. In this paper, we address the problem of querying a video database by images that might share some contents with one or more video clips. We present a new large dataset, called Stanford I2V . We have collected more than 3; 800 hours of newscast videos and annotated more than 200 ground-truth queries. In the following, the dataset is described in detail, the collection methodology is outlined and retrieval performance for a benchmark algorithm is presented. These results may serve as a baseline for future research and provide an example of the intended use of the Stanford I2V dataset. The dataset can be downloaded at http://purl.stanford.edu/zx935qw7203.
