摘要

针对肺部细胞病理图像亮度不均衡、异常细胞轮廓精准分割难以实现的问题，提出一种以U-Net为基本框架，结合稠密块以及注意力机制的异常细胞分割模型。首先，利用具有编码器-解码器结构的U-Net对异常细胞进行分割；然后，在U-Net中引入稠密块，以提高特征之间的传播能力，提取更多异常细胞的特征信息；最后，利用注意力机制提高异常细胞区域的权重，降低亮度不均衡对模型的干扰。实验结果表明，该方法的IoU和Dice相似系数值分别为0.6928和0.8060，与其他模型相比，提出的方法能够分割出低对比度区域和形状多样的异常细胞。

Abstract

Aiming at the problems of unbalanced brightness of lung cell images and achieving accurate segmentation of abnormal cell contour difficultly

an abnormal cell segmentation model based on U-Net was proposed

which combined the dense connection mechanism and attention mechanism. Firstly

U-Net with encoder-decoder structure was used to segment abnormal cells. Secondly

the dense block was introduced into U-Net to improve the propagation ability between features and extract more characteristic information of abnormal cells. Finally

the attention mechanism was used to increase the weight of abnormal cell regions and reduce the interference of the imbalance of brightness to the model. The experimental results show that the IoU value and Dice similarity coefficient achieved by this method are 0.6928 and 0.8060

respectively. Compared with other models

this proposed method is able to segment low-contrast regions and abnormal cells with diverse shapes.
