Algorithm of scalevariant objects tracking based on ellipse log-polar transform

More Information
  • To solve the problem of the traditional log-polar tracking method which could only catch up with circular and quasi-circular objects with scale changing, we introduced ellipse log-polar transform(LPT) to estimate the target-s scale parameters within the framework of Mean Shift tracking. Experimental results demonstrate that the composite algorithm has lower tracking error and better tracking accuracy rate on the condition of small deformation and light intensity changes. Comspoured with the traditional, it has a better robustness.
