This study introduces novel distribution distance metrics for visual tracking and image segmentation. These metrics offer a new approach to separating objects from backgrounds in images.

Area of Science:

  • Computer Vision
  • Image Analysis
  • Computational Mathematics

Background:

  • Current image segmentation methods often rely on maximizing intensity moment separation.
  • Geometric active contour models are widely used for object segmentation.
  • These methods can be computationally intensive and sensitive to noise.

Purpose of the Study:

  • To introduce and explain alternative metrics for quantifying distribution distances.
  • To demonstrate the relevance of these metrics in visual tracking applications.
  • To explore their utility in designing filters for image segmentation.

Main Methods:

  • Utilizing distributional metrics to define a flow that minimizes distribution changes.
  • Representing segmenting curves as zero level sets of signed distance functions.
