Visual System

Visual System

Light enters the eye through the cornea, a transparent, dome-shaped surface covering the surface of the eyeball that helps to direct and focus incoming light. This light is then channeled toward the pupil, an adjustable opening whose size is controlled by the iris. The iris, a pigmented muscle, regulates the amount of light entering the eye by contracting or dilating the pupil, thereby ensuring optimal light levels for clear vision.
Once through the pupil, the light passes through the lens, a...

Vision

Vision

Vision is the result of light being detected and transduced into neural signals by the retina of the eye. This information is then further analyzed and interpreted by the brain. First, light enters the front of the eye and is focused by the cornea and lens onto the retina—a thin sheet of neural tissue lining the back of the eye. Because of refraction through the convex lens of the eye, images are projected onto the retina upside-down and reversed.

Parallel Processing

Parallel Processing

The brain processes sensory information rapidly due to parallel processing, which involves sending data across multiple neural pathways at the same time. This method allows the brain to manage various sensory qualities, such as shapes, colors, movements, and locations, all concurrently. For instance, when observing a forest landscape, the brain simultaneously processes the movement of leaves, the shapes of trees, the depth between them, and the various shades of green. This enables a quick and...

Computer Vision
Artificial Intelligence
Biologically Inspired Computing

Background:

Effective integration of multi-scale features and contextual information is crucial for neural system structure modeling and complex visual tasks.
Existing models often struggle with balancing global and local feature representation efficiency.

Purpose of the Study:

To propose CompEyeNet, a biologically inspired hybrid neural network architecture.
To enhance multi-scale information representation and reconstruction capabilities for complex visual tasks.

Main Methods:

Developed a hybrid architecture combining transformers (MATBN) and lightweight convolutional structures (CENN).
MATBN utilizes multiple attention mechanisms for local and long-range dependencies.
CENN enhances high-resolution feature layers and attention fusion for multi-scale representation.

Main Results:

CompEyeNet demonstrated superior performance on medical image segmentation datasets (MICCAI-CVC-ClinicDB, ISIC2018, MICCAI-tooth-segmentation).
Achieved better performance with fewer parameters compared to Deeplab, Unet, and YOLO series.
Reduced parameters by 38.31% compared to YOLOv11, improving Dice, Jaccard, Precision, and Recall.

Conclusions:

CompEyeNet offers significant advantages in parameter efficiency and accuracy for neural system modeling and image analysis.
Bio-inspired attention-fusion hybrid neural networks show broad application potential.
