IEEE Transactions on Neural Networks and Learning Systems
|November 20, 2020
Summary
Analogy-detail Networks (ADNets) mimic human vision for object recognition. This novel convolutional neural network architecture improves accuracy by processing global shape and local texture features separately, outperforming existing models.
Area of Science:
- Computer Vision
- Artificial Intelligence
- Cognitive Science
Background:
- Human visual system excels at object recognition, handling complex textures and noise.
- Recent studies reveal a dual-pathway cognitive mechanism (analogy-detail) in human vision.
Purpose of the Study:
- To propose a novel convolutional neural network (CNN) architecture, Analogy-Detail Networks (ADNets).
- To mimic the human visual system's analogy-detail dual-pathway mechanism for accurate object recognition.
Main Methods:
- Designed ADNets with two distinct pathways: analogy (global features) and detail (local features).
- Modularized pathways into an 'analogy-detail block' as a CNN building block.
- Developed a principle to transmute typical CNNs into the ADNet architecture.
Main Results:
- ADNets significantly reduced test error rates of baseline CNNs by up to 5.76%.
- ADNets outperformed other state-of-the-art object recognition architectures.
- Demonstrated improved interpretability and a better shape-texture tradeoff for complex object recognition.
Conclusions:
- ADNets effectively replicate the human visual system's dual-pathway processing for enhanced object recognition.
- The proposed architecture offers a promising approach for accurate and robust object classification, especially with complex visual data.

454
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...

58.7K
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.

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...

Visual agnosia is a condition characterized by the inability to recognize visually presented objects despite having normal vision. For instance, a person with visual agnosia can describe the shape and color of an object but cannot identify or name it. This impairment does not affect their visual field, acuity, color vision, brightness discrimination, language, or memory. An example of this condition in a social setting is someone at a dinner party asking for "that silver thing with a round...
