The new CATUR network improves object tracking by adaptively updating templates based on confidence, enhancing robustness in challenging conditions like occlusion and appearance changes. This leads to more stable and accurate tracking performance.

Area of Science:

  • Computer Vision
  • Artificial Intelligence
  • Machine Learning

Background:

  • Siamese tracking is a popular object tracking method due to its efficient structure and feature matching.
  • Current methods struggle with template accuracy in complex scenarios like appearance changes, occlusion, and motion blur, impacting tracking stability.

Purpose of the Study:

  • To propose a novel Confidence-guided Adaptive Template update with Re-detection (CATUR) network for robust object tracking.
  • To enhance template accuracy and tracking stability in challenging environments.

Main Methods:

  • Developed a tracking confidence assessment module using Average Peak-to-Correlation Energy (APCE) and dynamic thresholds.
  • Designed an adaptive template update network combining initial, historical, and current-frame templates.
Keywords:
