基于深度主动学习的白带白细胞智能检测方法研究

Detection of white blood cells in microscopic leucorrhea images based on deep active learning

白带显微图像中白细胞的数量可以提示阴道炎症的严重程度。目前对白带中白细胞的检测主要依靠医学专家们的人工镜检,这种人工检查耗时、昂贵且容易出错。近年来,有研究提出基于深度学习技术对白带白细胞实现智能检测,但是这类方法通常需要人工标注大量的样本作为训练集,标注代价高。因此,本研究提出运用深度主动学习算法来实现对白带显微图像中白细胞的智能检测。在主动学习框架下,首先以少量的标注样本作为基础训练集,采用更快的卷积神经网络(Faster R-CNN)训练检测模型,再自动挑选最有价值的样本进行人工标注,从而迭代更新训练集和相应的检测模型,使模型的性能不断提高。实验结果表明,深度主动学习技术能在较少的人工标注样本下获得较高的检测精度,对白细胞检测的平均精度达到了90.6%,可以满足临床常规检查要求。

The number of white blood cells in the leucorrhea microscopic image can indicate the severity of vaginal inflammation.At present,the detection of white blood cells in leucorrhea mainly relies on manual microscopy by medical experts,which is time-consuming,expensive and error-prone.In recent years,some studies have proposed to implement intelligent detection of leucorrhea white blood cells based on deep learning technology.However,such methods usually require manual labeling of a large number of samples as training sets,and the labeling cost is high.Therefore,this study proposes the use of deep active learning algorithms to achieve intelligent detection of white blood cells in leucorrhea microscopic images.In the active learning framework,a small number of labeled samples were firstly used as the basic training set,and a faster region convolutional neural network(Faster R-CNN)training detection model was performed.Then the most valuable samples were automatically selected for manual annotation,and the training set and the corresponding detection model were iteratively updated,which made the performance of the model continue to increase.The experimental results show that the deep active learning technology can obtain higher detection accuracy under less manual labeling samples,and the average precision of white blood cell detection could reach 90.6%,which meets the requirements of clinical routine examination.
