摘 要:舌象中的裂纹是中医舌诊中的重要内容。由于拍摄条件的不同,舌象质量有较大差异,传统的阈值选取方法并不
适用。文中提出一种舌象裂纹检测的自适应阈值选择方法。该方法利用舌象的L 3 a 3 b 色彩特征及区域的分裂- 合并,
对舌象进行区域分割,自适应地选取舌中部区域的色彩值作为阈值,对整个舌象进行裂纹提取。经验证,本方案对不同的
舌象能较好地提取出裂纹,实现舌象裂纹诊断的客观化。-Tongue’ s crack is a very important part of herbal

通过引入特征点和改进最近点迭代法, 提出了一种
在三维扫描系统中对三维点云数据进行配准的方法。该方法
通过对特征点的提取, 首先得到一组匹配点对, 然后运用
SVD 矩阵分解算法求出转换参数R 和T, 进而以此作为最
近点迭代法的初始值, 并对最近点的求法和迭代截止条件作
了改进, 得到了很好的配准效果。该文论述了该方法的基本
原理, 并通过不同视觉下物体三维测量点云数据配准的应用
实例证明了该方法的有效性。-A 3-D meas uring dat a r egis

本文提出一种通过实时调整目标特征权值来进行背景自适应跟踪的算法。首先，定义了一种综合特征集合用以描述目标的颜色和局部轮廓。其次，提出了在滤波框架中对目标特征进行评估的算法，从而使得具有强区分能力的特征占有较大的权值，进而使其能够在跟踪过程起到较大的作用。采用传统的Kalman 滤波和粒子滤波对所提出的算法进行了验证。-In this paper, we propose a new adaptive visual object tracking method based on
