    This study introduces a deterministic model for monocular space perception. It reconstructs 3D spatial coordinates from retinal luminance changes caused by eye movements, utilizing optical flow analysis.

    Area of Science:

    • Computational Neuroscience
    • Visual Perception
    • Robotics

    Background:

    • Monocular vision presents challenges for accurate 3D spatial perception.
    • Understanding how the brain processes visual cues for depth perception is crucial.

    Purpose of the Study:

    • To present a deterministic computational model for monocular space perception.
    • To explain the reconstruction of 3D spatial coordinates from retinal luminance changes.

    Main Methods:

    • Analyzing retinal luminance changes caused by involuntary eye movements to determine angular velocity.
    • Employing infinitesimal transformations for 3D spatial coordinate reconstruction.
    • Deriving differential equations for optical flow and parallax field extraction based on the conservation of energy principle.
