The Digital Video and Multimedia (DVMM) Lab at Columbia University is dedicated to research of computer vision, machine learning, and multimodal content understanding. Our primary goal is to develop intelligent techniques and systems that can extract rich information and knowledge from data of rich modalities and their combinations, such as images, video, language, and audio.
Our work on content-based visual search in the early 90's set the foundation of this vibrant area. Over the years, we have developed innovative machine learning techniques and systems for image/video retrieval and recognition, event detection, hashing-based scalable search, and multimodal knowledge graph extraction. Our research results have been used in real-world applications, such as commercial video search engines, online human trafficking crime prevention, and brain machine interface products. Our impacts can be seen in peer-reviewed publications, best paper awards, 30+ issued patents, and technology transfer.
