Summarizing raw video material using Hidden Markov Models

Abstract

Besides the reduction of redundancy the selection of representative segments is a core problem when summarizing collections of raw video material. We propose a novel approach for the selection of segments to be included in a video summary based on Hidden Markov Models (HMM), which are trained on an annotated subset of the content. The observations of the HMM are relevance judgments of content segments based on different visual features, the hidden states are the selection/non-selection of content segments. The HMM is designed to take all relevant scenes into account. We show that the approach generalizes well when trained on sufficiently diverse content.
