摘要
舌体轮廓正确分割是实现中医舌诊信息化的重要前提。本文从如何对舌像进行定位与分割入手,通过研究阈值方法或先验知识在舌体轮廓提取时存在的缺陷,设想了用直方图均衡化预处理采集到的图像,然后根据舌体的形状、位置信息,对得到的初始轮廓线进行几何修正,基本解决了嘴唇对初始轮廓线的影响。
The correct is premise to the information on diagnosis by the feature of tongue in TCM. This paper starts from position and segmentation of tongue image and assumes using histogram equilibrium to deal with collected image because of flaw of threshold algorithm and prior knowledge in the course of extraction of contour of tongue, and then amending initial contour of the body of tongue by a geometric method according to the prior knowledge about shape and position of the tongue, which overcomes the edge influence on lip.
