Eye vein verification City, Kansas, company, markets eye vein verification with a system called Eyeprint. In 2012, EyeVerify licensed the technology developed and patented by Derakhshani. And Derakhshani now serves as chief science officer of EyeVerify. Eye vein verification Eye vein verification is a method of biometric authentication that applies pattern-recognition techniques to video images of the veins in a user's eyes. The complex and random patterns are unique, and modern hardware and software can detect and differentiate those patterns at some distance from the eyes. The veins in the sclera—the white part of the eyes—can be imaged when a person glances to
Evolution of the eye fast locomotion or navigation by vision. The rate of eye evolution is difficult to estimate, because the fossil record, particularly of the lower Cambrian, is poor. How fast a circular patch of photoreceptor cells evolve into a fully functional vertebrate eye has been estimated based on rates of mutation, relative advantage to the organism, and natural selection. However, the time needed for each state was consistently overestimated and the generation time was set to one year, which is common in small animals. Even with these pessimistic values, the vertebrate eye would still evolve from a patch of photoreceptor cells in
