    Textural segmentation relies on simple visual features like brightness and color, not complex statistics. This finding supports theories that local elements, or "textons," drive texture perception.

    Area of Science:

    • Visual perception
    • Computational neuroscience
    • Image processing

    Background:

    • Early theories proposed second-order statistics were key to textural segmentation.
    • Robert Beck hypothesized segmentation relies on simple stimulus properties.
    • Bela Julesz's initial conjecture on second-order statistics was later disproven.

    Purpose of the Study:

    • To test whether specific stimulus features or second-order statistics drive textural segmentation.
    • To evaluate the consistency of experimental findings with existing hypotheses on texture perception.

    Main Methods:

    • An experiment was conducted to analyze the factors influencing textural segmentation.
    • Stimulus features such as brightness, color, size, and contour slopes were examined.

    Main Results:

    • Experimental results support the hypothesis that specific stimulus features, not second-order statistics, are responsible for textural segmentation.
    • The findings align with Beck's hypothesis and Julesz's revised theory of 'textons'.

    Conclusions:

    • Textural segmentation is primarily driven by local, simple stimulus features.
    • The concept of 'textons' as local features explains texture perception effectively.
    • Current evidence supports a unified view of textural segmentation based on elemental features.
