一种基于先验知识的自动舌体分割算法
A Knowledge-Based Arithmetic for Automatic Tongue Segmentation
【摘要】 舌诊在中医望诊中有着重要作用 ,为了自动分析舌体的各项指标 ,必须将舌体从拍摄到的彩色图像中分割出来 .由于嘴唇和舌体部分的纹理复杂 ,在采用Snakes方法提取舌体轮廓时 ,很难得到理想的轮廓 .本文提出了一种基于先验知识的分割方法 ,利用舌体的位置、颜色等先验信息 ,取得了较好的分割效果
【Abstract】 Tongue Diagnosis plays an important role in the Inspection of Traditional Chinese medicine.In order to analyze the features of tongue body automatically,tongue segmentation should be done firstly.Because of the texture complexity of the tongue and the lip,it is difficult to abstract the accurate contour of the tongue body only with Snakes model.In this paper a knowledge-based arithmetic is adapted which makes full use of the tongue body’s information,such as position and color.
