If we can replicate the human visual system and to solve the problem of developing a computer vision system. So why can't we? The main difficulty that we do not understand what human vision system over time.
If you look at your eyes, maybe not clear to you that your color vision (by 6 million cones in the eye) is concentrated in the center of the Visual field (known as spot). The rest of your retina consists of about 120 million rod cells (sensitive to visible light of any wavelength or color). In addition, each eye big blind instead where the optic nerve attaches to the retina. Somehow, we believe we see continuously (no blind spot) with color everywhere, but even this minimum level of processing is clear on how that impression within the brain.
The visual cortex has been studied (in the back of the brain) and show contains cells that sort of edge detection, but most of them we know what brain sections done based on localized brain damage. For example, the number of people with damage to a section of the brain can no longer faces (a condition known as prosobagnosia). Other people have lost the ability to sense moving objects (a condition known as akinitobsia). These conditions inspired us to develop separate units recognition and motion detection of the object.
Can also look in the brain using functional magnetic resonance imaging, which allows us to see that the focus of the electrical activity in different parts of the brain as subjects perform various activities. Again, this may tell us what the major parts of the brain, but she could not provide us with algorithms for solving the problem of interpreting the huge arrays of numbers that provide video cameras.
