    Research - short version

    It is currently impossible to find most scientific, personal and social imagery because meaningful annotations describing the content are missing. My work will allow all imagery to be searched by developing new deep learning algorithms for automatic image annotation and by exploiting synergy between the user and the computer in novel interactive search paradigms.

    Research - longer version

    With the ubiquity of the Internet, social and streaming imagery and visual media, there has been an explosion of information that is now accessible to the entire world. The importance of the visual information can not be underestimated. It is a part of our daily lives and shapes how we experience and perceive and interact with the world. Other periods in history were dominated by materials for society survival (warfare), sustenance and growth. Surely, this time we live in is the "Age of Information." In particular, visual (and more generally multimedia) information is the fundamental pillar for shaping modern societies from personal events to elections of leaders to international news and politics and even waging conflict. One prominent characteristic of the mountain of visual information is that while it is indeed accessible, it is extremely difficult to search for a desired item - a needle in a mountain of haystacks. My group's mission directly addresses this problem. We investigate new paradigms for the computational retrieval and understanding of visual information by developing new deep learning approaches. Currently, keyword search (such as Google and Bing) is the dominant method for searching for information in large datasets. This works well for text documents, but the problem is that most of the images and video worldwide do not have annotation - e.g. the vast number of smartphone pictures typically only have date and location, not who or what was in the picture. In this case the only option is to use machine learning approaches to analyze the pictorial content of the images and video toward extracting keywords or models and then using those keywords (or models) for the search queries. More generally, we are also examining other media such as audio, text and 3D sensors toward exploiting all of the information (multimedia) toward higher accuracy and new query interfaces and results.
