TonguExpert aims to provide an integrate resource platform to archive tongue images and extract tongue phenotypes. Here, we release a database (DOWNLOAD HERE (~302M)) currently contains de-identified tongue images and tongue phenotypes from a cohort of 5,992 Chinese individuals, with a male to female ratio of 1: 1.26, with an average age of 46.55±13.21. A model integrated with multiple deep learning algorithms extracts phenotypes from raw images following the workflow below. Details of the model parameters can be found in our manuscript.
The database includes the following 697 phenotypes:
TonguExpert provides an integrated online platform based on multiple deep learning algorithms, designed to assist users in extracting fine-grained tongue phenotypic features and conducting classification from images containing human tongue features. Leveraging the effectiveness of multi-platform collaboration in precise graphic processing, we employ a series of deep learning algorithms for tongue segmentation, specularity removal, tongue coat and tongue body segmentation, color phenotype extraction, and morphological feature extraction (including tooth marks and tongue fissures) from raw images. Algorithms used by the workflow include SAM, ResNet50, YoloV8, SAM-adaptor, and VGG network are integrated with our scripts. The workflow have been described in DATABASE. See HEADER file for the output file format.
