A dataset of stained tongue fur images of TCM

Tongue diagnosis is one of the characteristic diagnostic methods of traditional Chinese medicine (TCM), and it is also an important basis for the diagnosis of diseases and syndromes in TCM. It mainly includes tongue texture and tongue fur. Tongue fur mainly includes tongue fur texture and tongue fur color, especially the tongue color is an important indicator to identify the nature of the disease. Clinically, tongue fur is easy to be stained by drugs and food, resulting in color illusion and misdiagnosis. This dataset recorded two kinds of tongue images of TCM, stained tongue fur and non-stained tongue fur, with an average of about 1000 tongue images for each type. The stained tongue fur data include the color change images of the tongue fur for 5 minutes, 10 minutes, and 30 minutes after eating stained food in health conditions of different populations. The colors are mainly divided into white, yellow, gray and black, with yellow predominating. Non-stained tongue fur data included pathological tongue fur images of different populations, which were divided into white, yellow and gray, and black fur. This dataset can provide a reliable classification basis for research in the field of tongue diagnosis, effectively solve the problem of tongue fur artifacts, and also provide data support for the development of more intelligent tongue diagnosis instruments.
