Digital Image Processing: Structure of Reading Notes and eyes

First look at the eye structure:

The eyes are still relatively complex, involving at least 10 of the following parts:

1. cornea, a hard and transparent tissue in front of the eyes, protects the eyes.

2. sclera. The surface outside the cornea is enclosed by sclera.

3. choroid, which contains vascular network, provides nutrients for the eyes.

4. The mascara body (ciliary body) is located at the anterior part of the target, and the fiber above it is responsible for suspension of the lens (lens)

5. Iris (IRIS) is also located in the anterior part of the suboder and controls the amount of light that enters the eye through contraction and expansion. The middle opening is the pupil.

6. the lens (lens) is suspended by the mascara fiber and can absorb a visible spectrum of 8%, which has a high absorption rate for short-wave long light. Proteins are responsible for absorbing infrared light and ultraviolet light.

7. The Retina (retina) is covered with the entire posterior wall. Light from outside the eyes is imaged on the retina. There are two types of optical sensors on the retina: cone-shaped and rod-shaped.

8. The cone-shaped body contains-, which is located in the middle of the retina and becomes a central concave area. Each Cone has its own nerve tip, which is highly sensitive to color and forms a daytime or bright vision.

9. There are 75-15000 rod-shaped bodies, and several rod-shaped bodies share one nerve tip. No color perception, used to give a general overall image within the field of view, sensitive to low brightness. Constitute a dark or low-light vision.

10. Blind spots. Blind spots can be seen wherever there is no optical receptor on the retina.
