Linear time-invariant Systems

A system is linear if it displays the characteristics of homogeneity and additivity, together termed the superposition property. This principle is fundamental in all linear systems. Linear time-invariant (LTI) systems include systems with linear elements and constant parameters.
The input-output behavior of an LTI system can be fully defined by its response to an impulsive excitation at its input. Once this impulse response is known, the system's reaction to any other input can be calculated...

Adaptive Linear Predictors (ALPs) enable fast online modifications for template tracking, efficiently handling size variations and occlusions. This method updates predictor inverses quickly, outperforming standard approaches in speed and accuracy.

Area of Science:

  • Computer Vision
  • Machine Learning

Background:

  • Real-time template tracking often requires fixed template sizes, limiting adaptability.
  • Standard linear predictors lack online modification capabilities for template shape variations.

Purpose of the Study:

  • To introduce Adaptive Linear Predictors (ALPs) for efficient online template size modification.
  • To develop a robust tracking system capable of handling occlusions and large templates.

Main Methods:

  • Proposed Adaptive Linear Predictors (ALPs) for fast online updates of linear predictors.
  • Implemented a fast inverse update method, avoiding computationally expensive full matrix inversions.
  • Developed a multilayer approach for occlusion detection and integrated ALPs for occlusion handling.
