So here I am reading a paper "A System for the Detection of Pigment Network in
Dermoscopy Images". I want to ask what actually is a pigment network?
thanks
A pigment network in dermoscopy images refers to the pattern of dark brown lines or streaks that can be seen on the skin's surface. These lines are caused by increased melanin in the deeper layers of the skin, and they can help identify certain skin conditions or abnormalities.
A pigment network is formed by the presence of melanin in the deeper layers of the skin. Melanin is a pigment that gives skin its color, and it can accumulate and form a network-like pattern when there is an overproduction of melanocytes (cells that produce melanin) or inflammation in the skin.
Different patterns of a pigment network can indicate various skin conditions or abnormalities. For example, a regular and symmetrical network is typically seen in benign moles, while an irregular and asymmetrical network can be a sign of melanoma. Other patterns, such as a branched, dot-like, or globular network, can also provide information about the type of skin lesion or condition present.
Yes, a pigment network can change over time. It can become more prominent or fade away depending on the underlying skin condition. For example, a melanoma may cause the pigment network to become more irregular and develop new features, while a benign mole may have a stable and unchanging network.
Dermatologists evaluate a pigment network in dermoscopy images by examining its color, symmetry, and other features. They may also use specialized tools, such as computer-assisted algorithms, to analyze and classify the pattern. This information, along with other clinical findings, can help determine the likelihood of a skin lesion being benign or malignant.
