Summary
This study classified brown Korean iris colors into seven groups and identified three basic and three complex iris patterns. These findings aid in creating realistic artificial eyes for cosmetic and reconstructive purposes.
Area of Science:
- Ophthalmology
- Color Science
- Biomedical Engineering
Background:
- The iris's color and pattern are crucial for artificial eye design.
- Limited data exists on the specific characteristics of brown Korean irises.
Purpose of the Study:
- To classify the colors and patterns of Korean irises.
- To provide data for the development of more realistic artificial eyes.
Main Methods:
- Utilized K-mean clustering image analysis on 100 Korean eye photographs.
- Converted RGB data to CIELAB color space for analysis.
- Grouped similar iris colors based on calculated color differences.
Main Results:
- Identified seven distinct brown iris color groups, varying in chroma and lightness.
- Classified iris patterns into three basic types (crown, sunshine, flower) and three complex mixtures.
- Determined representative colors and average hue values for each color group.
Conclusions:
- Established a classification system for Korean iris colors and patterns.
- This classification is applicable to the design of artificial eyes.

Color in Coordination Complexes
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...

1.5K
Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.

2.4K
Forces play a crucial role in the study of physics and engineering. They are essential in describing the motion, behavior, and equilibrium of objects in the physical world. Forces can be classified based on their origin, type, and direction of action.
Contact and non-contact forces are two of the most widely used categories of forces. As the name suggests, contact forces require physical contact between two objects to act upon each other. Examples of contact forces include frictional,...

01:30Classification of Neurotransmitters
5.3K
Neurotransmitters play a crucial role in the communication between neurons in the autonomic nervous system. Neurons in the autonomic nervous system can be cholinergic or adrenergic depending on the neurotransmitters synthesized. Cholinergic neurons use acetylcholine as their primary neurotransmitter. This includes all the preganglionic fibers of the sympathetic and pre- and postganglionic fibers of the parasympathetic nervous systems. In addition, neurons of the somatic nervous system also use...

01:30Classification of Leukocytes
6.0K
Leukocytes are classified into two groups based on the presence or absence of cytoplasmic granules. Granular leukocytes, which contain granules, belong to the myeloid lineage and are divided into three subtypes: neutrophils, eosinophils, and basophils. These cells are roughly spherical and characterized by the granules in their cytoplasm.
Neutrophils are the most abundant type of granular leukocytes, comprising 50-70% of all leukocytes. They feature small, evenly distributed granules and a...

8.8K
The meaning of illness is individualized to each person who experiences an alteration in health. In contrast, disease is a medical term indicating a pathological change in the structure and function of the body or mind. It is a condition that has specific symptoms and boundaries.
An illness is a response to a disease in which the person's level of functioning is changed compared with a previous level. The general classification of illness includes acute and chronic.
Acute illness is severe...
