Robust goal-mouth detection for virtual content insertion
Kong-Wah Wan, Xinping Yan, Xinguo Yu, Changsheng Xu · 2003
In this paper, we describe a working system that detects and segments goal-mouth appearances of soccer video in real-time. Processing on sub-optimal quality images after MPEG-decoding, the system constrains the Hough Transform-based line-mark detection to only the dominant green regions. The vertical goal-posts and horizontal goal-bar are then isolated by color-based region (pole)-growing. We demonstrate its application for quick video browsing and virtual content insertion.
