This study introduces a novel texture classification framework using random closed set theory. The method extracts distributional descriptors as features for accurate binary and grayscale texture analysis.

Area of Science:

  • Computer Vision
  • Image Analysis
  • Pattern Recognition

Background:

  • Texture classification is a fundamental challenge in image analysis.
  • Existing methods for texture analysis are diverse, but a unified framework is needed.
  • Random closed set theory offers a probabilistic approach to modeling spatial structures.

Purpose of the Study:

  • To propose a novel global framework for texture classification based on random closed set theory.
  • To adapt the framework for both binary and grayscale texture images.
  • To validate the effectiveness of the proposed method using standard texture databases.

Main Methods:

  • Representing binary textures as outcomes of random closed sets.
  • Utilizing distributional descriptors such as spherical and linear contact distributions and K-functions as texture features.
