This paper presents the framework and results of team Florida International University University of Miami (FIU-UM) for the semantic indexing task of TRECVID 2010. In this task, we submitted four runs of results: • F A FIU-UM-1 1: KF+RERANK apply subspace learning and classification on the key framebased low-level features (KF) and use co-occurrence(More)
In this paper, a hierarchical disaster image classification (HDIC) framework based on multi-source data fusion (MSDF) and multiple correspondence analysis (MCA) is proposed to aid emergency managers in disaster response situations. The HDIC framework classifies images into different disaster categories and sub-categories using a pre-defined semantic(More)
In this paper, we propose a Correlation based Feature Analysis (CFA) and Multi-Modality Fusion (CFA-MMF) framework for multimedia semantic concept retrieval. The CFA method is able to reduce the feature space and capture the correlation between features, separating the feature set into different feature groups, called Hidden Coherent Feature Groups (HCFGs),(More)
We present a novel visual analytics system and multimedia enabled mobile application that allows emergency management (EM) personnel access to timely and relevant disaster situation information. The system is able to semantically integrate text-based emergency management disaster situation reports with related disaster imagery taken in the field by EM(More)
The booming multimedia technology is incurring a thriving multi-media data propagation. As multimedia data have become more essential, taking over a major potion of the content processed by many applications, it is important to leverage data mining methods to associate the low-level features extracted from multimedia data to high-level semantic concepts. In(More)
Semantic concept detection is among the most important and challenging topics in multimedia research. Its objective is to effectively identify high-level semantic concepts from low-level features for multimedia data analysis and management. In this paper, a novel re-ranking method is proposed based on correlation among concepts to automatically refine(More)
Homeowner insurance is a critical issue for Floridians because of the periodic threat hurricanes pose to Florida. Providing fairness into the rate-making policy process, the state of Florida has developed the Florida Public Hurricane Loss Model (FPHLM), an open, public hurricane risk model to assess the risk of wind damage to insured residential properties.(More)
