提出了一种针对病理切片图像的端到端语义分割方法--边缘感知网络(BPNet),以提高病理图像分割精度。BPNet网络首先在解码器阶段增加边缘感知模块,改善网络对于病理图像边缘的特征信息提取能力。然后,采用自适应通道注意力模块弥补不同层次特征间的语义差距,进一步加强网络的特征聚合能力。在此基础上,设计了一种基于结构和边缘的联合损失函数,以实现最佳的病理图像分割结果。在GlaS和MoNuSeg两个公开病理数据集上的分割实验结果表明,所提方法的Dice系数得分在两个数据集上分别达到92.21%和81.18%,有效提升了病理图像的分割精度。

基于2003—2016年城市—国家对贸易数据,本文使用OLS和PPML模型考察地区市场潜力和地方保护主义影响城市出口的程度及作用机制。研究发现:(1)地区市场潜力显著提升了城市出口规模,地方保护主义则显著降低了城市出口规模。(2)改善地方保护主义将有利于发挥市场潜力的出口促进作用。(3)市场潜力和地方保护主义通过劳动力流动效应、创新效应和企业生存效应影响城市出口。本研究的结论为优化城市出口环境提供了新视角,也证明建设统一开放大市场的必要性。

针对目标场景复杂的空间布局和高光谱影像固有的空-谱信息冗余等挑战,提出了端到端的轻量化深度全局-局部知识蒸馏(Lightweight Deep Global-Local Knowledge Distillation,LDGLKD)网络。为探索空-谱特征的全局序列属性,教师模型视觉Transformer(Vision Transformer,ViT)被用来指导轻量化学生模型进行高光谱影像场景分类。LDGLKD选择预训练的VGG16作为学生模型来提取局部细节信息,将ViT和VGG16通过知识蒸馏协同训练后,教师模型将所学习到的远程上下文关系向小规模学生模型进行传递。LDGLKD可通过知识蒸馏结合上述两种模型的优点,在欧比特高光谱影像场景分类数据集OHID-SC及公开的高光谱遥感图像数据集HSRS-SC上的最佳分类精度分别达到91.62%和97.96%。实验结果表明:LDGLKD网络具有良好的分类性能。根据欧比特珠海一号卫星提供的遥感数据构建的OHID-SC可以反映详细的地表覆盖情况,并为高光谱场景分类任务提供数据支撑。
