结合密集连接块和自注意力机制的腺体细胞分割方法

Glandular Cell Segmentation Method Combined with Dense Connective Blocks and Self-Attention Mechanism

  • 摘要: 针对目前常用的细胞分割方法在对腺体细胞进行分割时易出现误分割和分割不精细的问题,提出一种以U-Net为基本框架,结合密集连接块和自注意力机制的腺体细胞分割模型.首先将U-Net结构中卷积层组合构建成密集连接块,以不同尺度从图像中提取信息;然后在解码端引入自注意力机制,通过对局部特征建立丰富的上下文依赖模型,抑制不必要的特征传播,提高腺体细胞分割的精度.在2015MICCAI腺体分割挑战赛数据集上的实验结果表明,与U-Net等其他模型相比,在增加少量参数的情况下,该模型在F1值、MeanDice和Hausdorff距离评价指标上均具有较大的提升.

     

    Abstract: Currently used cell segmentation methods are easily to cause the problem of missegmentation and impreciseness for glandular cell segmentation.A glandular cell segmentation model based on U-Net network is proposed which combines dense connective blocks and self-attention mechanism.Firstly,the convolution layers in the U-Net structure are combined to form the dense connective blocks,so that the information can be extracted from the image at different scales.Then the self-attention mechanism is introduced at the decoder to establish a rich context-dependent model for local features to suppress unnecessary feature propagation and improve the accuracy of glandular cell segmentation.The experimental results on the 2015 MICCAI Gland Segmentation Challenge dataset show that the proposed model,with a small number of extra parameters,can achieve improved performance in terms of F1-score,Mean Dice coefficient,and Hausdorff distance compared with other U-Net based methods.
