Area of Science:

  • Psychophysics
  • Computational Neuroscience
  • Computer Vision

Background:

  • Psychophysical experiments require stimuli with specific statistical and phenomenal properties.
  • Existing methods for generating stimuli may lack control over complexity and naturalistic appearance.

Purpose of the Study:

  • To present a method for creating pseudo-random stimuli with desirable features for psychophysical research.
  • To introduce multidimensional noise as a source for generating controllable and repeatable experimental stimuli.

Main Methods:

  • Derivation of stimuli from a pseudo-periodic function termed multidimensional noise.
  • Manipulation of noise properties to control stimulus complexity and self-similarity.
  • Implementation details for creating and utilizing these stimuli.

Main Results:

  • Generation of stimuli with controllable complexity and self-similarity.
  • Creation of stimuli exhibiting stochastic yet consistent and repeatable properties.
  • Successful application of these stimuli in shape and surface perception experiments.

Conclusions:

  • The proposed method provides a versatile tool for generating high-quality stimuli for perception research.
  • Multidimensional noise offers a robust foundation for creating naturalistic visual stimuli.
  • The presented stimuli are made available for broader use and further scientific discussion.
