Statistical models for automatic video annotation and retrieval
Victor P. Lavrenko, Siwei Feng, Raghaven Manmatha · 2004
We apply a continuous relevance model (CRM) to the problem of directly retrieving the visual content of videos using text queries. The model computes a joint probability model for image features and words using a training set of annotated images. The model may then be used to annotate unseen test images. The probabilistic annotations are used for retrieval using text queries. We also propose a modified model - the normalized CRM - which substantially improves performance on a subset of the TREC video dataset.
