    Depth Perception and Spatial Vision

    Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.

    Published on: May 10, 2024

  • Designed a novel residual depthwise-separable convolution module.
  • Created a tailored data-preprocessing module to filter noise and retain MI features.

    • Main Results:

    • ResDSNet achieved high accuracies on three public datasets: 79.36% (BCI Competition IV IIa), 84.95% (BCI Competition IV IIb), and 64.13% (PhysioNet).
    • Outperformed state-of-the-art methods by significant margins (3.16%, 1.59%, and 8.40%).
    • Demonstrated effective unlocking of hierarchical representation capabilities for robust MI-EEG decoding.

    Conclusions:

    • ResDSNet effectively overcomes the depth barrier in MI-EEG decoding networks.
    • The proposed method significantly enhances BCI performance by leveraging deep hierarchical features.
    • ResDSNet shows substantial potential for advancing BCI technology through improved EEG signal processing.
