| 摘 要： | 为了准确分割神经干细胞显微图像,尤其是成簇的正在分裂的细胞以获得神经干细胞分裂谱系,提出了一种改进的分割方法.在利用Otsu阈值法和简单快速的区域吞没法获取二值图像后,利用形态学迭代算法分割成簇的细胞.在二值图像中对每个成分进行特征提取和分析,噪声、欠分割和过分割的细胞以及成簇的细胞分别被提取出来进行处理.利用对起始帧的人机交互式修正及帧间信息可以提高分割正确率.统计结果表明,改进后的方法相比于传统的阈值结合分水岭的方法不论在节省时间还是正确率方面都有所提高,特别是针对成簇细胞和正在分裂的细胞效果尤为显著.

| Abstract: | Accurate segmentation of neural stem cells is very important,esp.for the clustered and splitting cells in order to acquire the information of neural stem cells' lineage.Otsu's threshold method and simple and fast region merging method are first applied to acquire binary image after preprocessing.To segment all clustered cells,an iterative morphology operation is then applied.Each component in segmented image is analyzed based on their characteristics.Noises,under and over segmentation,including splitting ce... |
