University of Kentucky professor Nathan Jacobs is researching ways to use computers to interpret and understand images of outdoor scenes. His efforts could provide new ways to understand images.

Jacobs has extracted patterns from large sets of images collected from Webcams and images uploaded from social networking sites. He also has built algorithms that use those patterns to make inferences and create predictions about what the images represent.

"They can be patterns that we use to understand the patterns themselves, or patterns that we use to understand things about the camera or the location that we're in," Jacobs says. For example, video of outdoor scenes could provide clues on how people move through them, and how movement changes based on different factors.

He says the pattern recognition could be used to detect and predict human movement, and characterizing normal movement patterns could be useful in several problem-solving applications.
