The DVMM Lab at Columbia University is dedicated to research of multimedia content understanding, computer vision, machine learning, and signal processing. Our primary goal is to develop intelligent systems that can harness rich information from the vast amount of visual data such as those shared on the open Web, collected through pervasive imaging devices, or stored in gigantic content archives. A consistent theme of our research is to turn unstructured multimedia data into useful and searchable information. Our work on content-based visual search in the early 90's, VisualSEEk and VideoQ, set the foundation of this vibrant area. Over the years, we continued to create new theories, algorithms and systems for image/video recognition, multimodal analysis, multimedia ontology construction, graph-based semi-supervised learning, and learning-based compact hashing for big data indexing. We also developed novel applications for multi-source news video aggregation, mobile visual search, and brain machine interfaces for large-scale information triage. With many high-impact publications and more than 30 issued patents, our results have been broadly distributed as open research resources and incorporated in practical systems in industry and government.
