舌象数据集

本数据集共包含舌象图像资料700份，其中每份图像数量不等；图像是在同一采集环境下，用使用道生四诊仪（DS-1）设备采集，拍摄时受试者取正坐位，并保持情绪稳定，采集舌象前嘱受试者避免食用带颜色的食物，避免染苔，必要时可漱口后再采集，分别取舌根、舌中、舌尖、舌边4个部位进行分割，并提取舌色、苔色特征。

This dataset consists of 700 sets of tongue image data, with a variable number of images per set. All images were captured under identical acquisition conditions using the Daosheng Four-Diagnosis Instrument (DS-1). During imaging, subjects were instructed to sit in an upright position and maintain emotional stability. Prior to tongue image collection, subjects were asked to avoid eating colored foods to prevent staining of the tongue coating, and to gargle before sampling if needed. Four regions of the tongue—root, middle, tip, and margin—were individually segmented, and features of tongue color and coating color were extracted.
