Topical Video Object Discovery from Key Frames by Modeling Word Co-occurrence Prior
2013
2013 IEEE Conference on Computer Vision and Pattern Recognition
A topical video object refers to an object that is frequently highlighted in a video. It could be, e.g., the product logo and the leading actor/actress in a TV commercial. We propose a topic model that incorporates a word co-occurrence prior for efficient discovery of topical video objects from a set of key frames. Previous work using topic models, such as Latent Dirichelet Allocation (LDA), for video object discovery often takes a bag-of-visual-words representation, which ignored important
