Human vision is an important way to perceive the objective world, people's vision has become important indicator of a person's health. the correct method of vision correction has become of great concern.This paper describes the human eye imaging, blurred vision and other physiological characteristics. Through eye chart test and the computer instrument, the research on human vision are carried out. Propose based-image algorithm on character properties and template matching, contrast the algorithm for different fuzzy image recognition. The proposed algorithm is more effective in Simulate the human eye to different visual acuity results and Significant for the visual detection. |
