Abstract

Whereas video tells a narrative by a composition of shots, current video retrieval methods focus mainly on single shots. In retrieval performance estimation, similar shots in a narrative may result in performance over-estimation. We propose an episode-based version of cross-validation leading up to 14% classification improvement over shot based cross-validation.
