This study introduces a quantitative method for generating vast numbers of binary and ternary textures. These textures offer diverse properties and enable the selection of specific image qualities for various applications.

Area of Science:

  • Computer vision
  • Image processing
  • Computational imaging

Background:

  • Generating diverse texture patterns is crucial for image analysis and synthesis.
  • Existing methods may not efficiently cover the vast combinatorial space of textures.

Purpose of the Study:

  • To present a quantitative method for creating a large number of binary and ternary texture classes.
  • To provide guidelines for selecting textures with specific image qualities or nonlinear pixel relationships.

Main Methods:

  • Development of a quantitative framework for texture generation.
  • Analysis of second- and third-order correlation functions for texture characterization.
  • Examination of several thousand texture examples.
