The HVS has two main components, the eye (input sensor) and the brain (information processing unit), connected by the optic nerve (transmission path) (Figure A.1). Image perception consists of capturing the image with the eye, then recognizing it, and finally interpreting its contents in the brain.
method for reconstructing viewed images from brain activi-ties, grounded on fundamental knowledge of the human vi-sual system. We craft reverse pathways that emulate the hi-erarchical and parallel nature of how humans perceive the visual world. These tailored pathways are specialized to decipher semantics, color, and depth cues from fMRI data,
• 1% of retina area but covers 50% visual cortex in brain – Adaptation of light intensity only through cones • Periphery: – 75-150 M. rods: night vision (B/W) – 5-7 M. cones (color) – Response to stimulation by single 1 photons (@ 500 nm) • 100x better than cones, integrating over 100 ms
The human visual system is a network of neural components that combine to create our perception of the world and guide our behavior. Deciphering the computational principles of this system is an important scientific challenge.
: Recent innovative neurological tests are described that are able to show much more accurately the visual pathways, the process of vision, and the close relationships among sensory modalities. These tests also reveal the remarkable neuroplasticity of the human brain and disorders of connectivity that frequently involve visual function ...
brain realizes visual perception and visual con-sciousness is correspondingly high. This chapter reviews our current state of knowledge about the systems-level functional anatomy of the hu-man visual system. The emphasis will be placed on the results of fMRI as a noninvasive imaging technique that combines structural informa-
The human visual system can be regarded as consisting of two parts. The eyes act as image receptors which capture light and convert it into signals which are then transmit-ted to image processing centres in the brain.
