Research Interests
With cost falling and computing power growing, the increasingly ubiquitous sensors are making possible a world in which "objects can sense, reason, communicate and act." However, the huge volume of data gathered by the sensors also introduces the challenge of how to extract insights and get useful information from the data. |
|
My research focuses on creating a robust and scalable framework that integrates noisy sensory data from heterogeneous sensors, e.g., surveillance cameras, RFID, fingerprint readers and infrared badges. By fusing and reasoning between multiple sensory data streams, we can derive a more accurate and consistent interpretation of the world, thus enabling a wide range of applications, including suspicious behavior detection, customer tracking in retail stores, asset monitoring and health care.
Recent Projects
- Multiple Sensor Indoor Surveillance: The proliferation of a wide variety of sensors (video cameras, microphones, infrared badges, RFID tags, etc.) in public places such as airports, train stations, streets, parking lots, hospitals, governmental buildings and shopping malls has created many opportunities for homeland security and business applications. Surveillance for threat detection, monitoring sensitive areas and detecting unusual events, tracking customers in retail stores, controlling and monitoring the movement of assets and monitoring elderly and sick people at home are just some of the applications that require the ability to automatically detect, recognize and track people and other objects by analyzing multiple streams of often unreliable and poorly synchronized sensory data. A scalable and robust system built for this task should also be able to integrate this sensory data with contextual information and domain knowledge provided by humans to maintain a coherent logical picture of the world over time.
- Community of Multimedia Agents(project co-leader): Challenges in multimedia analysis are calling for the consolidation of the research efforts, while in practice it is hindered by technical and proprietary issues. The project's objective is to solve the above problem by creating an open environment for developing, testing, learning and prototyping multimedia content analysis and annotation methods. Each method is represented as an agent that can communicate with the other agents based on Descriptors and Description Schemes in the coming MPEG-7 standard.
