摘要:

我们提出了一种弱监督细胞跟踪方法,该方法可以训练仅使用“细胞检测”的注释(即,细胞位置的坐标),其中细胞位置可以通过核染色容易地获得。首先,我们训练联合检测CNN,它通过使用弱标签来检测连续帧中的细胞。我们的关键假设是,协同检测CNN除了检测之外,还隐式地学习关联。为了获得这种关联,我们提出了一种向后和向前传播的方法,该方法分析了协同检测CNN输出中细胞位置的对应关系。实验表明,该方法通过分析协同检测CNN,可以实现细胞关联。即使该方法只使用弱监督,我们的方法的性能几乎是相同的国家的最先进的监督方法。代码可在https://github.com/naivete5656/WSCTBFP上公开获取

英文摘要:

We propose a weakly-supervised cell tracking method that can train a convolutional neural network (CNN) by using only the annotation of "cell detection" (i.e., the coordinates of cell positions) without association information, in which cell positions can be easily obtained by nuclear staining. First, we train co-detection CNN that detects cells in successive frames by using weak-labels. Our key assumption is that co-detection CNN implicitly learns association in addition to detection. To obtain the association, we propose a backward-and-forward propagation method that analyzes the correspondence of cell positions in the outputs of co-detection CNN. Experiments demonstrated that the proposed method can associate cells by analyzing co-detection CNN. Even though the method uses only weak supervision, the performance of our method was almost the same as the state-of-the-art supervised method. Code is publicly available in https://github.com/naivete5656/WSCTBFP
