| 摘 要： | 提出了一种基于相关向量机(RVM)的白细胞检出新方法.首先,借助RVM对一维直方图进行拟合,获得稀疏的相关向量.然后,直接从这些数量有限的相关向量中筛选出所需的阈值.最后,基于前一步得到的阈值,将完整、连续的白细胞区域从原始图像中分割出来.该方法已成功地应用于白细胞检出,有效地降低了由光照和染色引起的干扰.该方法计算效率高,无需设置额外参数.实验结果表明了该方法的优良性能.

| Abstract: | A new method for the white blood cell (WBC) detection is presented based on the relevance vector machine (RVM).Firstly,the sparse relevance vectors (RVs) are obtained while fitting the 1-D histogram by RVM.Then,the needed threshold value is directly selected from these limited RVs.Finally,the entire connective WBC regions are segmented from the original image.The method is used for the WBC detection.It reduces the interference induced by the illumination and the staining.It has advantages of the high computation efficiency and the no extra parameter setting.Experimental results demonstrate good performances of the method. |
