摘要
目的:基于深度神经网络DeepLab V3+建立结直肠息肉内镜图像语义分割模型。方法:选取Hyper-Kvasir数据库1000张、苏州大学附属第一医院500张结直肠息肉内镜图像,分为训练集(n=1200)和验证集(n=300),同时收集江苏大学附属金坛医院肠息肉图像作为测试集(n=220)。对内镜图像进行分割标记,载入以DeepLab V3+为框架的深度神经网络中训练,建立语义分割模型。结果:在内部验证集中,该模型的准确性(ACC)达97.2%,平均交并比(MIoU)达85.8%,Dice系数达0.924。在外部测试集中,ACC达98.0%,MIoU达80.1%,Dice系数达0.890。结论:基于DeepLab V3+深度神经网络,构建结直肠息肉内镜图像的语义分割模型,具有良好的预测性能,可作为检测结直肠息肉的有效工具。
Objective To establish a semantic segmentation model for colorectal polyps in endoscopic images based on DeepLab V3+.Methods A total of 1500 endoscopic images of colorectal polyps were collected,including 1000 from Hyper-Kvasir public dataset and 500 from the First Affiliated Hospital of Soochow University,and randomly divided into training set(n=1200)and validation set(n=300).Meanwhile,the images from Jintan Affiliated Hospital of Jiangsu University were collected as test set(n=220).After the endoscopic image segmentation and labeling,the images and masks were loaded into a deep learning neural network with DeepLab V3+as the architecture for training,thereby developing a semantic segmentation model.Results The accuracy,mean intersection over union,and Dice coefficient of the developed model were 97.2%,85.8%and 0.924 in the internal validation set,and 98.0%,80.1%and 0.890 in the external test set.Conclusion The DeepLab V3+based semantic segmentation model for colorectal polyps in endoscopic images exhibits excellent performances,and it can serve as an effective method for the detection and diagnosis of colorectal polyps.
