基于图像融合技术与改进Faster R-CNN的绝缘子故障识别

Gaoya dianqi
为提高地铁接触网绝缘子故障检测精度，文中提出一种融合双流注意力生成对抗网络（DSAGAN）与改进Faster R-CNN的检测框架。针对多源图像特征融合难题，通过DSAGAN实现接触网绝缘子红外与可见光图像的高效融合：生成器采用注意力机制强化关键特征提取，判别器引入最小二乘损失函数替代传统交叉熵，有效保留纹理细节并提升网络稳定性。在故障识别阶段，改进Faster R-CNN模型采用ResNet101替代VGG16作为主干网络，结合残差连接缓解梯度异常问题，并在RPN层嵌入非极大值抑制（NMS ...

人工耳蜗植入术后认知功能的神经影像学评估方法

Zhongguo tingli yuyan kangfu kexue zazhi
神经影像学方法可以对不同脑区进行定位和功能探索，为人工耳蜗植入后认知功能的神经机制提供重要信息。随着脑影像技术的发展，多种客观神经影像学方法用于评估人工耳蜗植入者的皮层功能。本文概述目前人工耳蜗术后常用认知评估的神经影像学方法，总结正电子发射断层成像和单光子发射计算机断层成像、近红外光成像、功能磁共振成像、经颅多普勒超声，以及脑磁图等方法在认知功能评估中的重要作用，旨在为人工耳蜗植入术后认知功能的神经影像学评估提供参考建议。
