Full Description
Artificial sight for the blind? We're not there yet, but this interdisciplinary guide explores the dramatic breakthroughs that now bring us to the brink. It is the first work that integrates the full range of physiological, engineering, and mathematical aspects driving the new technologies inspired by human sight, and explains the latest advances in everything from organic light sensors to devices that replicate spatial and temporal processing in the brain. Emphasizing both the devices and the software simulation point of view, the book provides retinal cell and primary visual cortex (V1) models that reflect our advancing understanding of visual signal communication networks. It explores design and fabrication considerations behind real-world implementations like semiconductor photosensors that mimic human rods and cones, circuitry that perform retinal processing, and wavelet-based visual detection systems. Engineers and researchers get the latest resolution and motion detection enhancement techniques, together with analytical tools needed to tackle the challenges ahead.
