Automatic Text Tracking In Digital Videos

We address the problem of automatically tracking moving text in digital videos. Our scheme consists of two separate processes: monitoring which detects the new text line entering a frame, and tracking which uses prediction techniques to reconcile the text from frame to frame. Temporal consistency allows one to monitor periodically and reduce the computation complexity. The tracking process uses a rapid prediction/search scheme to update the position of the text blocks between frames. We provide details of the implementation and results for text moving in the scene and text which moves as a result of camera motion.
