Relative Motion Analysis using Rotating Axes

Relative Motion Analysis using Rotating Axes

Consider a component AB undergoing a linear motion. Along with a linear motion, point B also rotates around point A. To comprehend this complex movement, position vectors for both points A and B are established using a stationary reference frame.
However, to express the relative position of point B relative to point A, an additional frame of reference, denoted as x'y', is necessary. This additional frame not only translates but also rotates relative to the fixed frame, making it...

To improve tracking accuracy and reliability in complex visual environments.

Main Methods:

An intelligent multi-part tracking algorithm was integrated to boost performance during partial occlusion.
A scale adaptive scheme dividing targets into four patches was employed for accurate scale estimation.
Novel Gaussian kernel functions were introduced to resolve location ambiguity caused by minor function value deviations.

Main Results:

The proposed tracker demonstrated significant improvements over state-of-the-art methods on benchmark datasets.
Enhanced robustness against partial occlusion was achieved through the multi-part tracking approach.
Accurate scale estimation and reduced location ambiguity contributed to superior tracking performance.

Conclusions:

The enhanced KCF tracker offers a powerful solution for challenging visual tracking tasks.
The integration of multi-part tracking, scale adaptation, and new kernels significantly boosts tracker robustness.
This work advances the field of visual tracking by providing a more reliable and accurate algorithm.
