摘　　要：为了深入地研究舌诊中舌下络脉,在HSI空间中,首先利用色度对饱和度信息的约束对舌下静脉血管进行了粗提取,然后分别用LUM滤波器和基于先验知识的像素聚类区域成长法进行去噪和最终轮廓提取.对150幅舌下图像的实验结果表明,其中113幅图像得到了较准确的提取结果,证明了本文所述方法的有效性.The researches focus on the tongue surface have been nearly accomplished, but rarely refer to sublingual vein which is also an important field in tongue diagnosis. This paper will firstly focus on the sublingual vein extraction in the HSI color space, taking use of the H component and S component, and then utilizing the prior knowledge to get the final contour of the sublingual vein. 113 images of 150 sublingual images get accurate results, which proved the efficiency of the method .
