| 英文摘要 | as digital video databases grow, so grows the problem of effectively navigating through them. in this paper we propose a novel content-based video retrieval approach to searching such video databases, specifically those involving human actions, incorporating spatio-temporal localization. we outline a novel, highly efficient localization model that first performs temporal localization based on histograms of evenly spaced time-slices, then spatial localization based on histograms of a 2-d spatial grid. we further argue that our retrieval model, based on the aforementioned localization, followed by relevance ranking, results in a highly discriminative system, while remaining an order of magnitude faster than the current state-of-the-art method. we also show how relevance feedback can be applied to our localization and ranking algorithms. as a result, the presented system is more directly applicable to real-world problems than any prior content-based video retrieval system. |
