| 摘 要： | 舌象分割是中医舌诊客观化研究中的一个重要步骤,其结果好坏直接影响到舌象自动分析结果.传统的snakes舌体分割算法的颜色依赖性太大,当舌象的采集环境发生变化时,该算法对所采集的舌象分割结果往往不能令人满意.本文提出的基于snakes模型的改进算法将舌象转换到多种颜色空间,两次应用Snakes动态轮廓模型,最大化地提取了...

| Abstract: | As tongue image segmentation is an important procedure in the tongue characterization,its accuracy affects the following automatic process directly.The traditional segmentation methods based on Snakes model rely on the color features of the tongue image seriously.When the acquisition environment has changed,the results obtained by the original methods are not usually satisfied.An improved approach based on Snakes model is adopted,which describes the tongue image in two other color space,uses a two-step Snak... |
