Based on the comparison results presented above, it is evident that the characteristics of the four algorithms under consideration are varied, and their distinct advantages and disadvantages are described below. The U-Net structure, based on the modification and expansion of a full convolution network, can obtain contextual information and precise positioning through a contracting path and a symmetrical expanding path. By classifying each pixel point, this algorithm achieves a higher segmentation accuracy and segments th...

Tongue observation is a widely utilized technique in traditional Chinese ethnic medicine (TCM). The color and shape of the tongue can reflect the physical condition and various disease properties, severities, and prognoses. For instance, in traditional Hmong medicine, the tongue&#39;s color is used to identify body temperature e.g., a red or purple tongue indicates pathological factors related to heat. In Tibetan medicine, a condition is judged by observing the tongue of a patient, paying attention to the color, shape, and moisture of the mucus. For instance, the tongues of patients with Heyi disease become red and rough or black and dry1; patients with Xieri disease2 have yellow and dry tongues; meanwhile, patients with Badakan disease3 have a white, humid, and soft tongue4. These observations reveal the close relationship between tongue features and physiology and pathology. Overall, the state of the tongue plays a vital role in diagnosis, disease identification, and evaluation of the treatment effect.
Simultaneously, owing to diverse living conditions and dietary practices among different ethnic groups, variations in tongue images are evident. The Lab model, established on the basis of an international standard for the determination of color, was formulated by the Commission International Eclairage (CIE) in 1931. In 1976, a color pattern was modified and named. The Lab color model is composed of three elements: L corresponds to brightness, while a and b are two color channels. a includes colors from dark green (low brightness value) to gray (medium brightness value) to bright pink (high brightness value); b goes from bright blue (low brightness value) to gray (medium brightness value) to yellow (high brightness value). By comparing the L x a x b values of the tongue color of five ethnic groups, Yang et al.5 found that the characteristics of tongue images of the Hmong, Hui, Zhuang, Han, and Mongolian groups were significantly distinct from each other. For example, the Mongolians have dark tongues with a yellow tongue coating, while the Hmong have light tongues with a white tongue coating, suggesting that tongue features can be used as a diagnostic indicator for assessing the health status of a population. Moreover, tongue images can function as an evaluation index for evidence-based medicine in clinical research of ethnic medicine. He et al.6 employed tongue images as a foundation for TCM diagnosis and systematically evaluated the safety and efficacy of Chou-Ling-Dan pellets (CLD granules-used to treat inflammatory and febrile diseases, including seasonal influenza in TCM) combined with Chinese and Western medicine. The results established the scientific validity of tongue images as an evaluation index for clinical studies. Nevertheless, traditional medical practitioners generally rely on subjectivity to observe tongue characteristics and assess patients&#39; physiological and pathological conditions, requiring more precise indicators.
The emergence of the internet and artificial intelligence technology has paved the way for digitizing and objectifying tongue diagnosis. This process involves using mathematical models to provide a qualitative and objective description of tongue images7, reflecting the content of the tongue image. The process includes several steps: image acquisition, optical compensation, color correction, and geometric transformation. The pre-processed images are then fed into an algorithmic model for image positioning and segmentation, feature extraction, pattern recognition, etc. The output of this process is a highly efficient and precise diagnosis of tongue image data, thereby achieving the goal of objectification, quantification, and informatization of tongue diagnosis8. Thus, the purpose of high efficiency and high precision processing of tongue diagnosis data is achieved. Based on tongue diagnosis knowledge and deep learning technology, this study automatically separated the tongue body and tongue coating from tongue images using a computer algorithm, in order to extract the quantitative features of tongues for doctors, improve the reliability and consistency of diagnosis, and provide methods for subsequent tongue diagnosis objectification research9.

objectification of tongue diagnosis in traditional medicine, data analysis, and study application

Tongue diagnosis is an essential technique of traditional Chinese medicine (TCM) diagnosis, and the need for objectifying tongue images through image processing technology is growing. The present study provides an overview of the progress made in tongue objectification over the past decade and compares segmentation models. Various deep learning models are constructed to verify and compare algorithms using real tongue image sets. The strengths and weaknesses of each model are analyzed. The findings indicate that the U-Net algorithm outperforms other models regarding precision accuracy (PA), recall, and mean intersection over union (MIoU) metrics. However, despite the significant progress in tongue image acquisition and processing, a uniform standard for objectifying tongue diagnosis has yet to be established. To facilitate the widespread application of tongue images captured using mobile devices in tongue diagnosis objectification, further research could address the challenges posed by tongue images captured in complex environments.

For the comparison results, see Figure 12, Figure 13, and Table 1, where the environment constructed by this study uses the same samples to train and test the algorithm model.
