"Our algorithm could be used to summarize videos captured by police officers while on duty or to summarize surveillance videos," says UCD Assistant Professor Yong Jae Lee.

In an interview, University of California, Davis assistant professor Yong Jae Lee discusses his computer vision research. "My research focuses on the design of algorithms and image representations that allow a machine to accurately recognize objects, their properties, and the activities of people appearing in an image or video with minimal human guidance," Lee says.

In one study, Lee developed an algorithm that automatically creates a short visual summary of a very long video taken by a wearable camera. The algorithm predicts the important people and objects the wearer interacted with, and uses those predictions to select the keyframes that go into the final summary. Lee says the technology could be used in a wide range of applications, such as summarizing police videos, creating video diaries, or examining videos taken by robots that are exploring new territories.

Lee says more can be done to increase interest in computer science, and he believes the key is to provide computer classes in elementary, middle, and high school. "Computer scientists will be in much need, as computers will become ubiquitous in almost all aspects of our everyday lives," Lee predicts. "If you are a creative person that likes to solve problems and think clearly and logically, then this is a field that you should definitely consider."
