| 摘 要： | 乳腺微钙化簇是早期乳腺癌的重要征象,计算机辅助的微钙化簇检测是医学影像领域的难题。为了提高检测系统的准确率,往往需要大量病灶标记,除了搜集样本本身的难度外,还需花费专家的大量时间。目前的研究工作很少涉及这个问题的解决方法。首次将基于主动学习的支持向量机技术应用到该领域,针对钙化簇感兴趣区域的特点,提出了选择训练集合的样本应该满足的基本条件。标准数据库上的实验证明,提出的方法能够大量地减轻样本标记的工作,并使乳腺癌微钙化簇检测系统的分类性能基本不变。 |

| Abstract: | Clustered microcalcification is an important signal for breast cancer in the early stages.However,computer aided detection of microcalcification is a challenge in the field of medical imaging.To improve the performance of the detection system,a large amount of lesion labeling is essential.Besides the difficulty on collecting samples itself,it also takes experts much time for manual labeling.Few state-of-the-art techniques take into account this problem W first applied the techniques of active learning with ... |
