Multicue HMM-UKF for real-time contour tracking

Yunqiang Chen, Yong Rui, Thomas S. Huang

Research output: Contribution to journalArticlepeer-review


We propose an HMM model for contour detection based on multiple visual cues in spatial domain and improve it by joint probabilistic matching to reduce background clutter. It is further integrated with unscented Kalman filter to exploit object dynamics in nonlinear systems for robust contour tracking.
