基于频域状态空间模型和注意力增强的胃早癌检测OA
Early Gastric Cancer Detection Based on Frequency Domain State Space Model and Attention Enhancement
胃癌是全球范围内发病率和死亡率均居高不下的恶性肿瘤,早期干预胃癌可以提高患者生存率,而胃镜检查是筛查胃早癌的最有效手段.近年来使用计算机技术辅助医学图像处理得到快速发展,为了提高胃早癌检测准确性,本文提出一种基于频域状态空间模型与注意力增强(Frequency domain State Space model and Attention Enhancement,FSSAE)的胃早癌检测网络.该方法通过频域状态空间模型(FSS)对胃镜图像的重要信息进行频域分析增强,提高胃早癌的识别准确度;并通过注意力增强模块(AEM)提高网络对癌变区域的聚焦能力.同时本文还引入新的损失函数来进一步提高网络性能.本文将所提出的FSSAE网络在构建的胃早癌数据集上进行大量实验,消融实验验证了FSS和AEM的有效性,对比实验结果表明FSSAE网络优于基准模型和其他网络,对比基线网络,FSSAE的AP指标提高了2.81%,提升了早期胃癌的检测准确性.
Gastric cancer remains a malignancy with high incidence and mortality rates worldwide.Early intervention in gastric cancer can improve patient survival rates,and gastroscopy is the most effective method for screening early gastric cancer.In re-cent years,the use of computer technology to assist medical image processing has rapidly advanced.To enhance the accuracy of early gastric cancer detection,this paper proposes an early gastric cancer detection network based on a Frequency domain State Space model and Attention Enhancement(FSSAE).This method enhances the frequency domain analysis of critical information in gastroscopic images through the Frequency domain State Space model(FSS),improving the recognition accuracy for early gas-tric cancer.Additionally,an Attention Enhancement Module(AEM)is incorporated to improve the network's ability to focus on cancerous regions.A new loss function is also introduced to further enhance network performance.Extensive experiments are con-ducted on the constructed early gastric cancer dataset using the proposed FSSAE network.Ablation experiments validate the ef-fectiveness of FSS and AEM.Comparative experimental results show that the FSSAE network outperforms baseline models and other networks,with the FSSAE's AP metric improving by 2.81%over the baseline network,increasing the detection accuracy for early-stage gastric cancer.
