We introduce a novel template update algorithm to prevent "drifting" in object tracking. This method improves template matching accuracy over traditional approaches.

Area of Science:

  • Computer Vision
  • Image Processing
  • Machine Learning

Background:

  • Template tracking, pioneered by the Lucas-Kanade algorithm in 1981, is a fundamental technique in computer vision.
  • A significant challenge in template tracking is maintaining template integrity over time, often leading to 'drifting'.

Purpose of the Study:

  • To address the issue of template 'drifting' in object tracking algorithms.
  • To propose and evaluate a new template update algorithm designed for improved robustness.

Main Methods:

  • Development of a novel template update algorithm.
  • Comparative analysis against naive template update methods.

Main Results:

  • The proposed algorithm effectively mitigates the 'drifting' phenomenon.
