Dense Tracking

Dense tracking aims to accurately follow the movement of all points within an image or video sequence over time, enabling detailed scene understanding and object interaction. Current research focuses on developing robust methods for long-term tracking, particularly in challenging scenarios like occlusions and significant appearance changes, employing techniques like neural implicit representations, self-supervised learning, and the fusion of multiple optical flows or tracking algorithms. These advancements have significant implications for diverse applications, including robotic manipulation, medical image analysis (e.g., endoscopic surgery and ultrasound), and the analysis of complex scenes like crowds or animal behavior.
