摘要：Due to the explosive growth of images and videos nowadays, multimedia computing, which focuses on techniques for organizing and searching large-scale multimedia data, has attracted intensive attentions from both researchers and industrial practitioners in the last decade. The “Wisdom of Crowds” refers to the collaborative utilization of multiple modalities or sources instead of relying on a single one alone for decision making, which has been successfully practiced in multimedia computing due to the multi-sourcing nature of multimedia data. In this talk, we introduce the recent research carried out by the Multimedia Computing Group of Sichuan University by using this philosophy, including 1) coached active learning, the first framework for modeling the user’s query intention in interactive video search; 2) in-class social network mining, the first automatic method for mining social interactions in classrooms based on a social network-augmented face recognition scheme; and 3) collocative near-duplicate retrieval, the first domain-specific method for near-duplicate image search that is specifically designed for merchandize image retrieval.
